Butcher (1970)

Underneath the frightening mask is a freak even more frightening than the mask itself. Broken soul full of pure hate. A perverted psycho who takes his flusters on innocent boys. The prison is in a slaughterhouse cages and when he gets a taste for fresh meat he chooses a suitable victim. He fuck them with his giant dick and their hopelessness and fear excites him. He is worst than hell it self. He is BUTCHER!
