Chile, 1989. Udo, an American wargaming champion, arrives at a sunny beach resort for a peaceful vacation with his girlfriend. When another tourist mysteriously disappears at sea, Udo decides not to search for his missing friend but to instead invite a mysterious local to play his wargame of choice — a tabletop game where players simulate the European theater of World War II. It’s a choice that begins to erode the boundary between game and reality, transforming the sunny beach into something far more dangerous — a reflection of Udo's own obsession with strategy and control, and his inability to conceive of violence as anything other than imaginary and theoretical.
