Mother's Day (1980)
When you go into the woods today, you're in for a big surprise. When you go into the woods today you're not going to believe your eyes. But it ain't no "teddy bear picnic". Three girls discover that two men are willing to do anything to impress Mother and what impresses Mother is watching her son commit acts of rape and murder. Now these women are prisoners and lowered to pawns in the game of checkers between two dim wits and their Maniac Mommy and the question becomes, can any of them escape, alive?
