What drives a woman to kill? And what drives her to do it six more times? Aileen Wuornos killed and robbed seven men between December 1989 and November 1990.

Aileen, a sex worker at the time, claimed that these men had either raped or attempted to rape her, saying that the homicides were committed in self-defense.
