History
In 1995, a young college student named Sophia Doyle gives birth to twin babies: a boy named Boone and a girl named Hester. Her sisters, except for one named Amy Meyer, leave her briefly to go dance to their favorite song. While they are gone, Sophia bleeds out and the sisters and Dean Munsch cover up the death, while Amy takes the babies. Amy commits suicide and the babies are left in the care of her sister, Jess Meyer, who becomes the Hag of Shady Lane to watch over them before eventually being institutionalized, along with the children. Jess becomes depressed for years until finally turning her sadness into anger and plotting her revenge. She teaches the two children how to murder and they eventually leave the asylum to finally enact their plan. Jess changes her name to Gigi Caldwell and kills the Red Devil mascot to obtain his costume. Hester and Boone break into Kappa to fill Melanie Dorkus' spray tan with acid and then a year later the two of them finally enroll at school, with Boone pretending to be gay, while Hester fakes scoliosis.

Pilot
An unknown person in a Red Devil costume is seen spying on the Kappa Kappa Tau sorority by soon to be pledge Grace Gardener who proceeds to follow costumed killer until he or she has disappeared into the night.

The next night Chanel Oberlin is preparing to enact a prank to scare the pledges into treating her with respect by dipping the sorority house maid Ms. Bean's head into the deep fryer. For the prank the deep fryer was supposed to be off, but Hester turned it back on. Chanel pushes Ms. Bean's head into the fryer not knowing it was on accidently killing her. She then intimidates the girls into hiding the body in the walk in freezer until it could be disposed of. It's implied that the Red Devil removes the body after everyone leaves as the body is gone when Chanel brings her boyfriend Chad to show him the body.

After deciding that she couldn't keep Ms. Bean's death a secret, Chanel #2 decides that she is just gonna go home. Leaving the other Chanels, she goes to her room to pack. As she begins to pack, she receives a text message that says "Brave enough to open the door?". Scared she walks to the door and opens it to see the Red Devil killer standing in her doorway. The costumed person then texts her "So do you want to dance with the devil?" to which she replies "Maybe" thinking that its just someone flirting with her. They begin to slow dance until the Red Devil texts her "I'm going to kill you now" causing a shocked Chanel #2 to reply "Wait, whaaaat???!". The killer proceeds to stab her in the shoulder with a butcher knife, causing her to respond by kicking the killer who falls to the ground. Chanel #2 then crawls towards her desk, intent on reaching her lap top, updating her twitter status to a plea for help telling her twitter followers that a person in a Red Devil costume is stabbing her to death. She is then stabbed in the back of the head, killing her, though she resurrects long enough to hit send on her status update before falling back down dead. Her body is found shortly after by the other Chanels, who think that Ms. Bean rose from the dead and killed Chanel #2.

Later on the same night, the pledges minus Grace, have been buried up to their necks in the Kappa yard. After a while, the buried pledges hear the sound of a lawn mower start and start to scream. However the deaf pledge Tiffany mistakes their screams for them singing and begins to sing Shake It Off by Taylor Swift before realizing too late that the girls were screaming. Boone, as the Red Devil, proceeds to run over Tiffany's head with the riding lawn mower.

Hell Week
Hester sneaks into the Dickie Dollar Scholar house and into Boone's room. He questions if he is supposed to be scared by her and the two of them stage his death.

At the end of the episode, Hester is shown walking into the morgue and opening up a drawer. Inside the drawer is Boone who is revealed to be alive, asking "What took you so long?" as he takes off the fake slashed throat.

Chainsaw
Chad and the members of the Dickie Dollar Scholar fraternity decide to get some pay back against the Red Devil and go out to look for the costumed killer. After finally taking the bait, Boone appears with a chainsaw. As the Dollar Scholars approach the Red Devil, they hear another chainsaw start up and look behind themselves to see that there is another person in a Red Devil costume: Hester. After a brief fight takes place where the Red Devils saw through each bat that is swung at them, Boone knocks down Chad Radwell, while Hester deals with the others, and is about to go in for the kill when another member of the frat named Caulfield screams "Chad Radwell" and goes in to protect him. Caulfield swings the bat at Boone, only to have his arm holding the bat sawed off. He then picks up the bat with his remaining arm and again swings the bat at the killer only to have his other arm sawed off. Boone then sets the chainsaw down and hits Caulfield in the head with the bat. Boone then picks the chainsaw back up and walks away into the night with Hester.

Haunted House
Through unknown means, the Red Devil had found former Kappa member Mandy Greenwell. As she watches her movie, she hears a knock on the door and goes to see who it is. Seeing that no ones there, she goes back inside and used a chair as a door block. She goes back to watch her movie as someone begins to shake her trailer scaring her into trying to find a place to hide. As she backs up, she bumps into something and turns around to see that its a person in a Red Devil costume. She screams in terror as the person raises the knife, and her screams continue as she is continually stabbed off screen. The next day the Red Devil poses the bodies of five or his or her victims in the Shady Lane house, and then texts Chad Radwell and Hester Ulrich, making them think that they texted to each other to meet at the house. But when they figure out that neither of them gave their numbers to each other, they go into the house anyways. Hester finds a bedroom to have sex with Chad in, and thinking that someone had made a replica of Ms. Bean's dead body out of wax, she touches it, only for her fingers to sink into the skin and realize that it was actually Ms. Bean's body. Chad bumps into the murphy bed as he freaks out, causing Shondell's body to tumble onto the floor, causing Chad and Hester to flee the room. As they run down the stairs to the basement, they find the dead body of the school's new mascot nailed up to the wall, and turn to run into a room to hide, only to find the room occupied by Chanel #2's body. They then run out the back door, only to see Mandy's body hanging from the roof in front of the back door, the two flee the house out the backdoor anyways. Later that night as Zayday, Grace, Pete, and Earl Grey search for the dead bodies that everyone is talking about, they see Mr. Bean and Shondell in the bedroom. Zayday continues to search for bodies as she calls the police, finding Coney's nailed to the wall and Mandy's hanging in front of the back door. As she argues with the police operator about her not making a fake call, she is grabbed by the Red Devil.

Pumpkin Patch
The Red Devil opens a latch in his or her lair, revealing Zayday, who is being held captive. As she begins to scream for help, the Red Devil closes the latch.

Later on the next night, Chanel #5 is sent to set up the Pumpkin Patch maze all by herself, as a punishment for conspiring against Chanel. She brings along twin brothers Roger and Dodger to keep her safe as she heads into the maze to set up the pumpkins. As she is setting up, the Red Devil approaches her from behind with a pair of hedge shears. She turns around and screams as the killer gets closer, causing Roger and Dodger to come to her and rescue her. As they are running through the maze to safety, the brothers make her choose between them. She argues that its not the best of times to have that discussion, but they pressure her to make a choice. She chooses Roger. Roger and her than run in one direction while an upset Dodger runs in a different one. Chanel #5 notices that they're leaving foot prints in the fake snow that will make it easy for the Red Devil to track them down. They then try walking back through their own foot prints, and Roger shouts to Dodger that he should do the same. As Dodger attempts to back track through his foot prints he trips and falls down. As he attempts to get back up, the Red Devil approaches him with the hedge shears. He begins to scream for Roger to save him, as Roger and Chanel #5 reach the exit of the maze. Roger attempts to go back and save Dodger, but Chanel #5 stops him. Dodger continues to scream, as he is gutted with the hedge shears off screen. The Red Devil then walks away as the camera pans down to Dodger's dead body.

Grace Gardner forms a search party to find Zayday, consisting of her father Wes, boyfriend Pete, Gigi Caldwell, and Denise Hemphill. Together they find the Red Devil's lair. However, the Red Devil shuts the power off leaving them in complete darkness. In the dark, the Red Devil attempts to attack Gigi and Denise, but Gigi manages to tase him or her. Denise goes to tell the others that they captured the Red Devil. However, when they get back to where the Red Devil was at, Gigi tells them that the Red Devil hit her on the head with a baseball bat and escaped down a laundry shoot.

Meanwhile, at the Kappa house, Chanel start the presidential vote hoping to win because of Zayday and Grace not being there. As she begins, Zayday shows up, and tells everyone the story of her capture and escape. She tells them that the Red Devil brought her up from the hatch, gave her roses, and served her favorite food to her, which he or she through some unknown means figured out. She tells them that she stabbed the Red Devil in the hand with a fork and escaped.

Later on Gigi is walking alone as someone begins to trail behind her. She hides herself behind a beam and waits for them to catch up. She then approaches the person, revealed to be the Red Devil, telling him or her that they're late. She goes on to reprimand the Red Devil for the way things spiraled out of control with Zayday. She then orders an unknown mans death, then walks away to get to her date with Wes.

Seven Minutes in Hell
During a slumber party that Zayday and Grace had planned to figure out the identity of the killer, the housing security is hacked by the Red Devil, trapping the girls in the girls in the house. Chanel calls her boyfriend Chad Radwell, who himself is bringing the guys from the Dollar Scholar frat on a panty raid of the Kappa house, to come and save them. He agrees to come and get them out. Once they reach the Kappa house, Chad sets a latter against the window, and climbs up it. Chanel, happy to be rescued says that if he saves her, she'll be his forever, causing him to stop in his tracks. He demands that she take the forever part back before he saves her, and she says that she'll be his for the amount of time he deems appropriate. He then breaks the window and climbs in. As he looks out, he notices the Red Devil approaching and tells the other guys to hurry up the ladder. Earl Grey and Roger make it up the ladder and through the window. As Caulfield, who is now armless due to an earlier encounter with the Red Devil, attempts to climb up the ladder, the ladder is tipped over by the Red Devil, causing him and the ladder to fall down. The Red Devil then proceeds to chop into his stomach twice with an axe before decapitating him with the same axe.

Later on that night, everyone begins to play truth or dare. Grace asks Sam what Chanel #3's deepest darkest secret is, and Sam reveals that Chanel #3's father is Charles Manson. Angered that Sam broke her trust and revealed that secret, Chanel #3 dares Sam to go into the basement and lay in the tub. As Sam walks into the basement, she asks if anyone else is down there, and says she doesn't like to be jumped out at. She sees the bathtub and approaches it. As she reaches it, the Red Devil pushes her to the ground causing her to hit her head on the tub. The Red Devil then picks her up and places her into the tub. Sam then requests that before she dies, the Red Devil reveal his or her true identity to her, which the Red Devil obliges. Sam then pleads that the Red Devil doesn't have to kill her, that she could help, to no avail as the Red Devil suffocates her with a piece of plastic sheeting.

A little later on, after almost being caught coming on to Chad, who has gotten over his attraction to her, Hester makes an unseen trip to the basement. While that's going on, the other girls being to play Seven Minutes in Heaven, starting with Chanel and Chad. Towards the end of their turn, they hear a scream from the basement, and go to see what's going on. Hester reveals that she has found Sam's dead body in the tub and Chanel accuses her of being the killer. During that time, Chanel #5 and Roger are having their turn in the closet. Roger reveals to Chanel #5 that he feels a little relieved that Dodger is dead, saying that they've never spent a moment apart since their birth. He goes on to say that he's sad that they'll never be able to use their secret clicking language again though, before realizing that he could just teach Chanel #5 the language. As he begins to teach her, she notices the Red Devil approaching him from behind. The Red Devil then proceeds to kill Roger by shooting him three times in the head with a nail gun. The Red Devil then unloads the rest of the nails in the gun into Roger's face after he's fallen to the ground, dead. The Red Devil then glances at Chanel #5 and leaves. Chanel #5 then screams, and everyone rushes up to see what's going on. Chad sees Roger's body and is devastated. Chanel accuses Chanel #5 of being the killer since she was alone with Roger when the murder happened. She then accuse both Hester and Chanel #5 of working together killing people, before accusing Pete for not even being there when the killings happened. She then reveals that there are secret tunnels that only the sorority presidents know about, that the killer could be using. Zayday volunteers to go down and search the tunnel for a way out. Chanel volunteers to go with her.

As Zayday and Chanel make their way through the tunnels, they are attacked by the Red Devil. As they run away, Zayday trips and falls to the ground, as she gets up and tries to run, the killer blocks her way with an axe, then as she turns towards the other direction, the killer blocks her way with another axe. However, the Red Devil is knocked out with a pan from behind by Chanel, letting her and Zayday make their escape.

The next day, Dean Munsch says that the killings have taught her one thing, that only the Kappas and people associated with the Kappas are being targeted by the Red Devil. She goes onto say that she's glad that she can tell parents that as long as their child isn't in Kappa or associated with Kappa, they're safe.

That same evening, the girls have bonded though the experience, and decide to dance to songs from a playlist. As Hester shouts "KAPPA", the Red Devil can be seen peering through the window.

Beware of Young Girls
Gigi can be seen receiving a call from one of the Red Devils, in which she makes it known how angry she is that the person who she ordered the Red Devil to kill hasn't been killed. She then tells the person on the phone that they are not kidnappers, they are killers bent on revenge, and that anyone of them that stray from that need to be killed, and that she wants the person who's death she ordered in "Pumpkin Patch" killed.

Also, Dean Munsch used the Red Devil's killing spree to murder her ex-husband and frame his death on the girl he left her for, Feather McCarthy.

Mommie Dearest
Dean Munsch is shown in her bathroom getting ready to take a shower. As she begins to soap up, the door can be seen opening and Hester can be seen approaching the shower with a knife. However, Dean Munsch is not in the shower, having anticipated being attacked. She proceeds to slam Hester into the shower rod and then into the bathtub. Once he is laying on the floor, she runs out to dial the police. However, the automated message is too long and it gives the Red Devil time to get up and attack her again. She moves towards the fire place and grabs the poker. As the Red Devil approaches her, she begins to strike him with the poker until he again falls to the floor. Cathy then drops the poker and runs to the door, only to open it and have her exit blocked by another Red Devil who is carrying an axe. Cathy mentions that two on one isn't fair, and then a third person approaches her, dressed in a Supreme Court Justice Antonin Scalia costume. Cathy mentions that during her junior year of college, she dated a "beautiful Eurasian man" and in exchange for teaching him to make love, he taught her to fight. She then proceeds to take on all three of the masked killers, knocking all three of them to the ground before the one in the Justice Scalia costume tries to attack her again. She then shoves the Scalia costumed killer into the wall and proceeds to punch the killer repeatedly in the face as she criticizes the real Justice Scalia's political stances. All three killers flee, having not been able to kill Cathy.

The next evening, Jennifer is seen making her candle vlog. As she is ranting about poor customer service she's received at a candle store in the mall, she is stabbed in the head by one of the Red Devil killers.

After hearing about Earl, Chanel #5 says it's not safe and leaves. When driving, a truck is heard honking their horn many times behind her until she reaches a gas station and pulls over. The truck driver gets out of his truck and #5 kicks him in the groin. He tells her that he saw someone in her backseat and he would flash his lights and honk his horn to make him hide. They walk over and see the backseat empty. Out of nowhere, the killer appears behind him and stabs him with a machete as #5 screams and rushes to her car and drives away while the Red Devil finishes the trucker off.

There's a knock on the door and Gigi answers for room service, the bell boy sees the Red Devil and looks confused and she asks him for a carving knife.

Dorkus
In flashbacks we see Pete donning the Red Devil costume killing Roger (Pete admits he didn't know if it was Roger or Dodger, stating the two were hard to tell apart) with the nail gun. He then admits to being the one in the costume who killed Boone, in an attempt to end the conspiracy/revenge plot. He also admits to being a part of the conspiracy to bring down the horrors of the American Greek system. Pete also tells Grace that she is safe from the killers, due to the fact that being their half-sister they don't want to kill her. He goes on to explain that he was also the killer at the mall and had killed the mall cop in self defense, Pete then says he took DNA from everyone in the KKT house to discover who Boone's twin and the other killer is. As he's about to reveal who she is, the Red Devil bursts out of the closet and stabs Pete in the back of the neck, killing him. The Red Devil then knocks out Grace after a brief struggle.

A pizza man is forced into the Red Devil costume with TNT strapped to his person, in an attempt to kill all the girls in the house at once. He is quickly subdued by the girls after he stops and is scared by the snake Chanel was attempting to kill herself with. He tells the girls he's going to explode and that he was attacked by someone in the costume, forced to wear it and then covered in explosives. The timer on his suit counts down from 5, stops for a second when it hits zero but then is blown completely apart. Strangely though, not destroying the cape or the mask.

The Final Girl(s)
The beginning of the episode starts one month past the events at the KKT house, January 2016. It shows the remaining survivors of the house being Grace, Zayday, and Hester. Upon seeing Hester it goes into her own voiced over monologue of how she was able to successfully place the blame of her self-inflicted attack on the Chanels. We discover that the female baby in the bathtub was Hester all along. A back flash ensues showing us Hester's life in the asylum and determination of the plan. While sitting in a cafe discussing with Gigi that the costume they wear should be as memorable as Jason's hockey mask or Freddie's sweater, the schools mascot walks in to make an announcement. Later that night they kill the original mascot so they can take the Red Devil costume.

At the end of the episode, the last we see is the Red Devil standing over the bed of Chanel with a butcher's knife in its hand, ready to stab her. Chanel screams and then it cuts to black. In season 2's, Warts and All, it is revealed that the Red Devil behind that mask was Chad Radwell, joking around with Chanel.

Scream Again
Hester only appeared in the beginning of the episode in footage from a VHS tape Denise Hemphill used as evidence to testify for the release of the Chanels. In the video, Denise is shown interviewing Hester in a locked room. Hester admits that she orchestrated the entire Red Devil conspiracy, but tells Denise that she can't convict her, because it's double jeopardy, and you can't be tried for the same crime twice. Denise argues with her that she hasn't even been tried before, since the Chanels were tried the first time. Hester still insists that it's double jeopardy, because someone was still convicted. After Denise demands that it's single jeopardy, Hester begins to lash out and starts beating the door down to get out. She ends up getting arrested for the Red Devil murders at Wallace University, while the Chanels are released and all charges against them are dropped.

Warts and All
This episode marks Hester's first appearance in the present time and shows her being locked up in maximum security. Denise Hemphill suggests to Cathy that Hester might know more about the intentions of the Green Meanie killer, hence she was a serial killer herself. Cathy, Denise, Chanel and Chanel #3 then go to visit Hester in prison. Her cell is covered with various pieces of artwork, and after #3 compliments the drawings, Hester states that they are all from memory, as she does not have a view of the outside world. When Chanel is about to ask if she knows anything about the recent killings at the C.U.R.E Institute, Hester already knows what they came for. She tells them that she knows who the killer is and that they have a connection to the Halloween Massacre that happened thirty years ago. Hester insists that she will tell them everything she knows if she can transfer to the C.U.R.E hospital, have a room with a view, and receive high-end beauty products which haven't been produced in the last ten years.

Handidates
Dean Munsch and the Chanels visit Hester due to the sudden death of Tyler and the disappearance of Randal. Hester tells them that she will not give them anything until she get's moved to the hospital to a room with a view. As a response, Munsch offers her the movie "A Room With A View". Hester, annoyed, tells the group to not toy with her for the body count was about to go through the roof. Unfortunately for Hester, Munsch denies her access to the hospital and leaves due to Chanel receiving a text from Chad saying he knew who the killer was.

Later, Denise Hemphill and Zayday bring Hester to the basement of the C.U.R.E Institute Hospital where they put her in a jail suit and question her. Denise demands to know who the killer is before another victim falls dead. Hester laughs and tells them that it's too late.

Halloween Blues
After Chad Radwell was killed, Cathy Munsch and Denise Hemphill try to come up with a way to find out the killer's identity, so they ask Hester, who suggests throwing a Halloween party inside the hospital, as they suspect the killer to be a member of the hospital staff. She then requests to attend the party, which Cathy and Denise deny; however, after Denise is attacked by the Green Meanie, she ultimately lets Hester go to the party, but she is not allowed to leave the hospital and has to wear an ankle bracelet that tracks her whereabouts. Moreover, she's supposed to dress up as Jason Voorhees, but she ends up copying Chanel #5's idea and goes as Ivanka Trump, Donald Trump's daughter. Shortly after she is released, she tries to attack Chanel Oberlin while disguised, and Chanel ends up suspecting #5 to be the one who tried to kill her and conclusively be the Green Meanie. Later that night, Hester actually attends the party, still disguised as Ivanka Trump. She doesn't do anything until a certain point after the party when #5 is carrying around stuff. #5 suspects it to be Chanel, who wants to take revenge on her. Hester pulls out a knife and slowly moves closer to #5, but lets it down when she sees her ally, the Green Meanie, who shoves a machete into her back. Hester leaves after that.

Chanel Pour Homme-Icide
Because of Denise's death, Hester can now freely roam the hospital. She lures Chanel into a room and scares her before telling her that she knows Chanel needs more Chanels and asks to rejoin the group. Chanel, desperate for more human shields for the Green Meanie, agrees. Hester moves into Chanel's apartment and suggests that they use Tristan St. Pierre (Chanel Pour Homme) as bait for the killer. Sadie insists that they use Chanel #8 instead, but ultimately, Chanel Pour Homme is killed anyways when the Green Meanie disembowels him off-screen when he wanders away from the slumber party the Chanels throw at the hospital.

Hester is the only person not fazed by the mutilated corpse and even smiles when she sees it. Later, Dean Munsch adds Chanels 9, 10, and 11. Chanel sends them away (and #11 is killed) before telling Sadie, Chanel, and Libby that Hester is missing and she is almost certain that the Chanels harbored a known serial killer.

Blood Drive'
When Hester starts to get homicidal do to boredom, Chanel convinces Dean Munsch to let Hester work in the hospital under the alias "Donna Summer." She assigns her a patient named Brandon Szathmary, who believes he is a vampire, whom Hester begins treating immediately and concludes he has Cutaneous Porphyria, and a weird blood addiction. She then treats this by feeding him so much blood that he will never want to even see blood. She gets the blood from Chamberlain who asks her if she was the serial killer who escaped her cell and is somehow working there, to which she replies "yeah." She continues treating the patient and succeeds in curing him.

After Chanel #9 is found killed via blood loss, Munsch and Chanel immediately blame Hester because she is a serial killer and she needed blood for her patient. Hester uses Chamberlain as an alibi and tells them that she got the blood from him. Unbeknownst to them, Nurse Hoffel and Doctor Cascade were the real killers of #9.
