Wen, only seven years old, is vacationing with her two dads, Eric and Andrew, at a remote cabin. While catching grasshoppers, she is approached by a stranger named Leonard. Initially friendly, he explains that he needs Wen and her parents' help to save the world. However, Wen becomes suspicious when three other people appear with makeshift weapons.

Leonard and his companions claim that they have never met before this day and have no intention of harming the family. However, in the past week, they have been driven by visions and an unknown force to find the family as they are predicting an impending apocalypse. Vision or illusion?
