Based on a true story, House On The Hill is a true crime account with strong horror elements, chronicling the outrageous 1980s murder spree of serial killer Leonard Lake, who would target, kidnap, rob and kill people - and even whole families. Private investigator Paul Kale locates the only survivor of Lake's killing spree, who is living in seclusion years after her escape from the Lake's 'sex slave' compound. She and Paul reluctantly team up to uncover the fate of a woman who disappeared into Lake's house of horrors. In the process, Sonia recounts her experiences and relates the murder and abuse she witness, where Lake and his accomplice would force her to video tape the kidnappings and killings.
