Werner Krauss, who had played the deranged Dr. Caligari six years earlier, stars as a scientist who is tormented by an irrational fear of knives and the irresistible compulsion to murder his wife. Driven to the brink of madness by fantastic nightmares (designed by Ernö Metzner and photographed by Guido Seeber in a brilliant mix of expressionism and surrealism), he encounters a psychoanalyst who offers to treat the perplexing malady.
