An ex-government agent (Kirk Douglas) is determined to find his son (Andrew Stevens) who was kidnapped by a secret intelligence organization. His son has telekinetic powers and the agency wants to use those powers for their own nefarious purpose. The ex-agent's only hope in finding his son is a troubled teenage girl (Amy Irving) who also has telekinesis abilities. Based on the novel by John Farris (who also did the screenplay), Brian De Palma's insane film is one crazy horror extravaganza. It's not the kind of film where one places too much attention to the plot or it would fall apart. The narrative is there for De Palma to push the edges of the envelope (for its time) of the supernatural horror genre. Visually, and with great assistance from Richard H. Kline's superb camera work, De Palma tosses out some great set pieces. There's the out of control amusement ride which is a homage to Hitchcock's STRANGERS ON A TRAIN finale and a breathtaking tour de force sequence where Amy Irving escapes from the institute, filmed in slow motion with no dialog and only John Williams' underscore. Speaking of which, Williams' Herrmannesque score is a corker! The piece de resistance, of course, is John Cassavetes' horrific yet hilarious exit from the film. With Carrie Snodgress, Charles Durning, Carol Rossen, Dennis Franz, Daryl Hannah, Rutanya Alda and Laura Innes.
