Death Rides a Horse

Bill (John Phillip Law), a boy whose father was killed and mother and sister were gang raped and murdered in front of him by a gang of four, sets out 15 years later to exact revenge, having used the time to become an expert marksman with a gun. Each of the outlaws bears a characteristic that Bill memorized while watching his family slaughtered and his house set on fire: the first has a tattoo of four aces on his chest, the second a scar, the third one a distinctive earring and the fourth (who was the one who saved young Bill from the burning house) wears a necklace bearing a skull; while he saw the face of the fifth, he never saw the face of the man who saved him from the fire.
