Biography
Mrs. Patterson taught at Winston High School and was married to the principal. Though the marriage was rough, as the principal was sexist and would cheat on her. While tutoring a handsome senior jock named Billy Corbin, Mrs. Patterson fell in love and the two began an affair. On the side, however, Billy was dating another student named Annie Morgan. One month later and on the night of Homecoming, Billy tries to charm Annie into having sex with him, but she refuses. Feeling angry, Billy tries to rape Annie, but Annie's friend Loren comes to her rescue and bashes Billy in the head and locks him in the janitor's closet. While trying to get out, Billy knocks over some candles and ends up burning to death. Despite the backlash the school got, neither Loren or any of the other students are charged.

Three years after Billy's death and nearing the next Homecoming celebration, Mrs. Patterson plots her revenge. She steals and sharpens the school's spirit baton and steals the janitor's firefighter gear. Annie, still traumatized by the incident, stays home from school, and the next day, Mrs. Patterson pursues her at her house and kills her. With Annie dead, Mrs. Patterson targets the rest of the group on the night of Homecoming, eventually ending when she kidnaps Loren and brings her to a room full of the corpses of her dead friends. She reveals herself, explains her motives, and pours gasoline on all the bodies. Before she can light a match, however, Jaclyn smacks her in the head with a flashlight. The two wrestle over the flashlight while Loren works to escape her binds. Mrs. Patterson is able to overpower Jaclyn and nearly beat her death with the flashlight, but Loren tackles her and she ends up being impaled on the spirit baton and supposedly dies.

However, some time after, Loren and Jaclyn are attending a graduation ceremony, when someone in a graduation gown slips the spirit baton out of their sleeve and follows them into the school.
