Elise (Britt Ekland) is the much younger second wife of Paul (Hardy Krüger), who married her soon after the loss of Sarah from drowning in a tub. Three months into their honeymoon of a marriage, she’s surprised by his 12-year-old son Marcus (Mark Lester, the star of Oliver), who claims that he’s left school early due to a chickenpox epidemic. The film wastes no time letting us know that not only is Marcus weird, he may also be a criminal sociopath.

After their first meeting, in which Marcus confesses to stealing money from his father, Elise looks through the child’s room and soon learns from the headmaster (Harry Andrews) that he was kicked out of school for stalking, creating sexual drawings and killing numerous small animals. She’s obviously worried and Paul just says that his son needs to get over the death of his mother.

That’s when this movie gets weird, as you wonder if Paul just doesn’t care that his son is a lunatic or if he’s just as much of a mentally ill person. Why wouldn’t he tell his new wife that the house they’re attending a party at used to be his and the place where Sarah died? Elise isn’t all that mentally set either, as she’s convinced to strip nude for Marcus if he’ll reveal the truth about killing his mother after she finds a hole above her bed and figures out that he’s been watching her.

That’s when Dr. Viorne (Lilli Palmer), who owns that house where Sarah died, listens to Elise’s concerns. She turns it around on her and accuses her of trying to seduce Marcus, as well as killing the family dog, a crime that was definitely committed by the young man. Elise loses her mind and tries to kill the boy before she’s put in a mental hospital where she dreams of being torn to pieces by the dog, as well as her killing Marcus and making love to him — not the same dream, this isn’t a Joe D’Amato movie — while Paul watches.

Marcus has, of course, been planning this all along. He asks Elise, when they are finally alone, if she wants to have an affair as his father is now too old to satisfy her. She kisses him passionately before…well, that would give up the ending, right? You really need to see this for yourself. The last ten minutes go for it and just unleash everything that could upset people about this movie.

This was directed by James Kelley, who also directed and wrote The Beast In the Cellar, and Andrea Bianchi, the maniac who made Cry of a Prostitute, Strip Nude for Your Killer, Malabimba and Burial Ground. It was written by Bautista Lacasa Nebot, Erich Kröhnke, Trevor Preston and Bianchi, so was supposedly brought in by another lunatic, producer Harry Alan Towers,  to add more exploitative scenes to the film.
