A young couple (Francisco Barreiro, Laura Caro), panicked when their kids (Michele Garcia, Alan Martinez) vanish during a vacation trip to the mountains outside Tijuana, are relieved when they turn up the next day, seemingly unharmed. The relief proves short-lived, though, as the children's increasingly disconnected behavior points to some hidden trauma...perhaps caused by something not of this Earth.
