One of the most gruesome Hammer horror films the studio ever made, and a dizzying high-concept premise to boot: what if the young daughter of Jack The Ripper became possessed by the spirit of her nutzoid father and continued his bloody legacy of murder? As an infant, Anna watches on in terror as her dad brutally dispatches with her mom. Years later under psychoanalysis, Anna discovers the possibility that she herself is now consumed by the Ripper’s true evil!
