Rosso sangue
Mikos Stenopolis (George Eastman) is a man who was experimented on in a church-sanctioned scientific experiment that gave him a healing factor, but inadvertently drove him insane. The Vatican priest (Edmund Purdom) who helped create him pursues the homicidal Mikos to a small American town, attempting to kill him by impaling him on a set of railings which disembowel him, but he is revived later in a local hospital. The madman escapes after brutally murdering a nurse, and goes on a killing spree. The priest informs the hospital and authorities that the only way to kill Mikos is to 'destroy the cerebral mass'.
While attacking a motorcyclist after escaping from the hospital, Mikos is struck by a hit-and-run driver. The driver of the car, Mr. Bennett, and his wife are going to a friend's house to watch a football game, leaving their two children at home with a babysitter. Their daughter Katia is confined to her bed because of a problem with her spine, while her younger brother believes that the 'Bogeyman' is coming to get him.
Mikos makes his way to the Bennetts' home, and begins to murder everyone there. Peggy, a family friend, is stabbed in the head with a pickaxe, and the babysitter has her head forced into a lit oven and is stabbed in the throat with a pair of scissors, but not before sending the brother off to get help. Katia struggles from her bed to take on the killer herself. Mikos breaks into Katia's bedroom and attacks her, but she manages to stab him in the eyes with a set of drawing compasses. She then stumbles down the hallway as the blinded killer staggers after her. He stalks her through the house, but Katia manages to elude him. The priest arrives and struggles with Mikos, and Katia grabs an axe from a decorative suit of armor and decapitates Mikos with it. The police and the rest of the family arrive to discover Katia standing in the doorway, covered in blood holding Mikos's severed head.
