It's Alive

Cult favorite about an ordinary couple who become the parents of a bouncing baby boy. Unfortunately, the infant is a grotesque monster who embarks upon a grisly killing spree throughout Los Angeles! The cops attempt to track down the blood-thirsty babe, as the parents (who have no idea how or why this happened) try to cope with this unusual ordeal. Ahhh, the joys of parenthood...
