The first part in the film is actually called "The Facts in the Case of M. Valdemar", directed by George Romero. The story concerns a cheating wife who is trying to scam her dying husband out of millions by having her doctor/hypnotist lover hypnotise the geezer into signing his dough over to her. The old man dies while under hypnosis and is stuck in the limbo between the here and the hereafter. The door to the physical world is opened and the undead attempt to enter it. The second part is "Black Cat", directed by Dario Argento. It's the story of an alcoholic artist who descends into madness after he kills a stray cat that his wife brings home. One murder leads to another, and the coverups become more complex.
