In this chiller from Italian director Mario Bava, Elke Sommer stars as Lisa, a young tourist who keeps running into a strange bald man who carries around a mannequin. The bald man is Leandre (Telly Savalas), the butler at the estate of a blind Countess (Alida Valli) and her slightly off-kilter son Max (Alessio Orano). In a bizarre turn of events, Lisa kills a man in self-defense and winds up hitching a ride with Frances Lehaf, his wife Sophia (Sylva Koscina), and her chauffeur/lover George. Car troubles land them at the Countess estate where Lisa is plagued by strange dreams and visions of the man she killed. More troubling for Lisa is that both the dead man and Max appear to know her. Meanwhile, the other guests begin to die: George is murdered by an unseen assailant, Sophia runs over her husband with the car, and then is dispatched herself by a killer who is revealed to be Max. Lisa awakens in Leandres room full of dummies and runs off through the house. She encounters Max, who shows her the skeletal remains of Eleanor, the lover he killed for having an affair with his stepfather. Max believes that Lisa is Eleanor reincarnated. After an odd sex scene, he is confronted by his mother whom he winds up stabbing to death. Moments later, she reappears and the shock sends Max falling to his own death. Lisa awakens in the house, which now appears to have been abandoned for decades. She boards an airplane to head home, but in a chilling climax, she discovers the plane devoid of all passengers...except for a few old friends including the diabolical Leandre. ~ Patrick Legare, All Movie Guide
