John Carpenter's Night Terrors: Sour Candy

Phil and Adam look like an ordinary father and son. Perhaps the boy dresses a little strange and seems to have an unusual hold over his old man. Perhaps the father looks hollowed out and sick. What no one knows is that until a few weeks ago, Phil had never seen the boy before, but now Adam is in his life, altering and controlling it, and it will take a special kind of horror to get him out.
