The true-life story of Aileen Wuornos, a prostitute executed in 2002 in Florida after being convicted of murdering six men. While Wuornos confessed to the six murders, including a policeman, she claimed to have killed only in self-defense, resisting violent assaults while working as a prostitute.In 1989-90, a love story unfolds in the midst of the horrors and pathologies of two misfits: Wuornos, a drifter prostitute and Selby Wall, sent by her parents to live with an aunt in Florida in order to "cure her homosexuality". Nearing suicidal despair, Aileen wanders into a bar, where she meets Selby and falls in love. To keep her and Selby's relationship alive, she continues hooking, only to fuel an increasingly escalating deadly rage, a fury vented with a lurid string of killings and the media's sordid designation of her as the first female serial killer--a monster.
