Naschy plays Marcos, a criminal who takes refuge in a house peopled by a wheelchair-bound, impotent man and his horny wife and daughter. Before long Marcos is pitting one family member against the other as he pleasures himself with the females. Marcos' immorality is caused by his own family tragedy, the murder of his mother by his father, which he witnessed when a child. He is a man who out of psychological necessity must debase the family unit and rage at anyone who says a bad word about his deceased mom. Marcos also lost his hearing during this traumatic incident in his childhood (the father hits him in the head before he does the deed), so besides the emotional scars left on Marcos, there is a physical one. Thus Naschy creates a novel villain who carries a framed photo of mom in his suitcase and wears a hearing device in his ear. Besides which, Naschy has never looked better--lean, tight, even handsome in an Elvis Presley sort of way, if you can believe it. Taken from The Mark Of Naschy
