In 1990, Florida police were on a frantic search for a killer. Seven men were dead, their bodies scattered along state highways. Terrorized motorists heard of the bullet-ridden victims of the Interstate Killer - but the investigative trail was cold and there was no end in sight. The killer behind the spree was Aileen Wuornos-a complex, misunderstood misfit who hitchhiked near truck stops, selected her victims at random, and lured them to secluded locations. It took good old-fashioned police work, a little luck, and a lover's betrayal, to finally bring Wuornos' killing spree to an end. This episode features rare interviews with victims' family members, and Wuornos' best friend.
