Wuornos had a difficult and cruel childhood plagued by abuse and drug use in Michigan. She became a prostitute by the age of thirteen, the same year she became pregnant. She eventually moved to Florida where she began earning a living as a highway prostitute–servicing the desires of semi-truck drivers. The tale focuses on the nine month period between 1989 and 1990, during which Wuornos had a lesbian relationship with a woman named Selby. And during that very same time, she also began murdering her clientele in order to get money without using sex. This turned the tables on a rather common phenomena of female highway prostitutes being the victims of serial killers–instead Wuornos, herself, carried out the deeds of a cold-blooded killer.
