A troubled boy kills his father with his farm tractor and in the process his arm is severely mutilated. He's taken to a mental institution where he's outfitted with a hook to replace his lost hand. Years later he is released from the asylum and returns home to find his mother remarried, thus triggering his murderous rampage.
