8 episodes. World War III is about to break out, and a group of billionaires takes refuge in a luxury bunker: Kimera Underground Park. From there, they watch on screens, in a bewildering spectacle, as the world they knew collapses around their heads. And while the situation outside becomes increasingly terrifying, they enjoy their exclusive little town with a basketball court, restaurant, Zen garden, cocktail bar, psychologist’s couch, gym, and spa. This is all their mythical privilege will be reduced to: adapting to living in a luxurious hole, in an underground universe full of enigmas where the unfinished business of two families haunted by a wound from the past will explode.
