The first episode ,'The Neighbour', a likeable young couple move into a new flat below a gentleman who has just murdered his wife. Argento cronie Luigi Cozzi directs. The second, 'The Tram', is the only episode officially directed by Argento himself, a whodunnit set aboard a crowded tram. The third, 'Eyewitness', tells of a nice young girl who witnesses a murder only for the body and all trace of the crime to have vanished upon returning with the police. The fourth episode 'The Doll' is credited to director Roberto Pariante but Argento apparently extensively re-shot it, features an escaped mental patient stalking young women through the streets of Rome. Directed by Mario Foglietti, although Luigi Cozzi directed some scenes. Last feature is a documentary on Argento produced in the late 80's to promote 'Opera'.
