Alan (Anthony Steffen) is a wealthy aristocrat who has just been released from a mental institution following the death of his wife, the red-haired Evelyn.

Having caught Evelyn making love with an unknown man prior to his institutionalization, the psychotic Alan begins luring red-haired strippers and prostitutes to his home to torture and kill them, as a way to deal with his grief and inability to get revenge on his deceased wife.

George Harriman (Enzo Tarascio) - Alan's cousin and his only living heir - offers to move into the mansion to take care of him.

However, Alan appears along with Richard Timberlane (Giacomo Rossi Stuart), the doctor who treated him for his first mental breakdown.
