Criminal Carlos "El Gato" is executed in the electric chair.Carlos is then resurrected by a creepy demoness called the 'Supreme Being of Darkness',but he has to renounce his religion,and spend his time raping and murdering people:each human sacrifice must be marked with a "666".Soon the orgy of brutal violence and rape is set in motion...Very sleazy and offensive Mexican exploitation trash.The rape scenes are brutal and rather unpleasant,and the level of sexual violence is very high.Even a young homosexual man is viciously stabbed to death and raped by sexually insatiable El Violador Infernal,who then carves "666" on the corpse's buttocks.The special effects are inept and the acting is mediocre,however fans of strikingly nasty low-budget exploitation won't be disappointed.8 out of 10.
