Close Encounters of the Family Kind
Brother and sister Derek and Emma embark on a seemingly innocent camping trip to drink a few beers and hang out away from their nosy mom. But their quiet escape is disturbed when they go to investigate what appears to be a crash landing of a UFO, only to discover that their long-lost father lives on board. Once the siblings are lured on board by Dad, however, they discover that the aliens can control them through some kind of mind control—and that they are obsessed with incest. After lustful Emma is rapidly deflowered by her brother, her father is next—and the aliens are just getting started.
