Violent Shit

A young boy named Karl Berger (a surname given in the sequel) murders his abusive mother with a Cleaver (knife), after she beats him for returning home late. Twenty years later, in the mid-1970s, the imprisoned Karl is being transported to an unspecified location by the police, but manages to kill his captors and escape into the wilderness, somehow acquiring a cleaver in the process. Over the course of several days, Karl commits a series of murders across the countryside, mutilating and occasionally Cannibalism his victims. After one double homicide, Karl faints and has a flashback to the day he murdered his mother, revealing he had been coerced into killing her by a demon (which a line of dialogue indicates may be his father) he had encountered in the cellar after being locked in it.
