An alien craft crash lands outside of a small town. The creature piloting the craft finds itself stranded in "Dad's Junkyard". Unfortunately it can't breath in Earth's atmosphere and the air from its ship is quickly escaping. The alien finds Jan, a girl who has recently killed her sexually abusive father. The terrified creature probes Jan, rather intrusively, and the strongest image in her mind is that of her father. It takes on the form of the dead, abusive, violent, sexually depraved, "Dad" and begins to stalk a group of teens stranded on the outskirts of town. A lone, unarmed deputy, and the vengeful, crazed Jan are all that stands between the stranded motorists and the murderous monster.
