Antonio Maghardt's first and most controversial horror film. A young man bet with a friend that he went alone to a haunted castle for the night. He met and fell in love with a beautiful female ghost on the way, but then fell in the plot of a group of ghosts. Magcht is also a character who has contributed numerous outstanding works to Italian horror films. In this film, he makes full use of black-and-white photography and the claustrophobia of the castle itself to create a sense of fear, and gives the film more violent and pornographic scenes. Far beyond the acceptability of the moviegoers at that time.
