Biography
As a child, Amy Elliot was the inspiration for her parents to create Amazing Amy, a series of popular children's books. The character of Amazing Amy earned tremendous spite from the real-life Amy, who constantly lived under the shadow of the seemingly flawless version of herself that her parents created. Later in life, she meets Nick Dunne at a party, who is a writer like she is. They quickly hit it off and begin a relationship, becoming married two years later, which greatly pleases Amy, as it is the only thing that Amy can share with her literary counterpart (Amazing Amy gets married in the final book of the series).

Their marriage is going great until the 2008 recession, causing them both to lose their jobs. On top of that, her parents request a large sum of money that nearly drains Amy's trust fund and thus her and Nick's finances, putting their marriage on the rocks. At the height of all of this, Nick's mother is diagnosed with Stage 4 breast cancer, forcing Nick and Amy to move from their townhouse in Manhattan, New York to a home outside of St. Louis, Missouri, where Nick gets a job as a creative writing teacher while he cares for his ailing mother.

After the death of Nick's mother, Nick and Amy's relationship continues to decline, Nick only seeming to give Amy attention when they are having sex. After purchasing a bar for Nick (which he runs with his sister, Margo), Amy later finds him with Andie, a student of his. After realizing that she is being cheated on, she puts her grand scheme into motion.

She begins by befriending a frequently-pregnant neighbor, Noelle, whom Amy deems "the local idiot." She later begins to purchase many expensive electronics with credit cards she put in Nick's name to create credit card debt, has Nick increase her life insurance for her, buys a cheap getaway car, writes bogus diary entries that exaggerate and fabricate Nick's physical abuse towards her and her fears of him murdering her, and fakes pregnancy by stealing Noelle's urine.

On the night before Nick and Amy's anniversary (where Nick was going to ask Amy for a divorce), she plans a scavenger hunt with objects connected to his betrayal: the diary (which she partially burns in the furnace of Nick's father's home), a pair of Andie's panties, and the electronics with a box containing a Punch and Judy puppet set. The next morning, she sets up her faked murder, rigging the house to imply a struggle, killing, and quick cover-up by knocking over picture frames on a rickety shelf and putting them back, drawing her own blood that she spills on the kitchen floor and mopping it up, and putting her blood on a blunt object which she burns in their fireplace.

By the time Amy leaves, Nick discovers and reports her disappearance. The neighbors (namely Noelle) and authorities soon suspect Nick in Amy's quickly apparent murder, causing him to be crucified on national TV and ostracized by his family and community (which is heightened by the fact that Amy was supposedly pregnant when "murdered").

Meanwhile, Amy drastically changes her appearance and starts a new life as "Nancy," drawing thousands of dollars in cash to support herself. She later meets her new neighbors, Greta and Jeff, who don't suspect a thing about her or her previous life. One night, Greta and Nick catch Amy with her money, prompting them to break into her house and violently rob her, leaving her penniless.

She then comes into the re-acquaintance of Desi Collings, a wealthy former boyfriend of hers who has grown obsessed with her. Knowing she staged her death because of Nick (whom she says was abusive towards her), he takes her into his lavish lake house nonetheless and promises to keep her safe and be a good lover.

One night, Nick goes on national television with the help of his sister and his defense attorney, where he admits to cheating on Amy with Andie, but denies murdering her. Amy and Desi both watch as Nick gives a heartfelt apology (as well as some subtle inside jabs relating to her scavenger hunt) about his betrayal.

With her love for Nick now renewed, she uses Desi's security camera system and a wine bottle to convincingly set herself up as a violently-abused rape victim. That night, Amy lures Desi in for sex, where she slashes his neck with a box cutter and covers herself in his blood. The next morning, Amy arrives to Nick's home in Desi's car, covered in blood and looking frightened, all in front of the numerous news outlets parked on Nick's street. Desi is blamed for Amy's kidnapping, and the authorities are more than willing to believe her story (except for 1 of the cops who first met Nick at the beginning of the film who seems to be suspicious of her but no longer allowed to question Amy and despite the glaring holes within).

While Nick is no longer tied to Amy's murder, his victory is still a Pyrrhic one. After Nick's admittance to his affair and Amy's return, he is forced to stay with her despite his loathsome feelings that he now harbors for her. Otherwise, it will appear as if he had abandoned her once again in the media eye, losing the respect he had just gained back. Also, she reveals to Nick that she is pregnant (quite possibly with Desi's child), further cementing Nick to her (if not, for the sake of his soon-to-be child). Nick is now trapped in his relationship with the homicidal, cunning and manipulative Amy for the rest of their lives.
