In London, the merchant Mike Roscoe (Ian Ogilvy) and his girlfriend Nicole (Elizabeth Ercy) go to a nightclub to dance. When they meet their friend Alan (Victor Henry), he dances with Nicole while Mike goes to a nearby bar. Meanwhile, the hypnotist Prof. Marcus Monserrat (Boris Karloff) has developed a piece of equipment for controlling minds and decides to seek out a guinea pig on the streets to test the device. He meets Mike in the bar and invites him home, where he introduces his wife Estelle Monserrat (Catherine Lacey) to the youngster. They test the system on Mike, controlling his mind and sharing his feelings. However the wicked Estelle enjoys the sensation and decides to use Mike in evil acts, and Marcus is incapable to control his wife. What will Estelle do with Mike and will Marcus succeed in stopping his deranged wife?

"The Sorcerers" is an atmospheric horror movie with an original story. Catherine Lacey has an impressive performance in the role of a wicked old lady that becomes addicted in sensations of the youth and transgressions. Susan George has a minor part in the beginning of her successful career. My vote is seven.

Title (Brazil): "Sob o Poder da Maldade" ("Under the Power of the Malevolence")
