Imagine that World War III is about to break out and a group of billionaires takes refuge in a luxury bunker: Kimera Underground Park. Through screens, they'll watch the bewildering spectacle of the world they knew collapsing above their heads. As the situation outside becomes increasingly terrifying, they'll enjoy an underground city with basketball court, restaurant, zen garden, cocktail bar, psychologist's couch, gym and spa. Their ancient privilege will be reduced to a life adapted to a luxurious hole, an underground universe full of enigmas where a wound from the past will explode between two conflicting families.
