    Its about serial killer who kills with hammer
    All i remember is the end of the movie when i think father find out
    that his son (i think) is the killer and he disappointingly turns his back and the kid kills him with blow on the head
    I watched it in the eighties and i was like 7 year old so memory very vague .
