The action takes place in the near future, against the backdrop of an impending Third World War. The world stands on the brink of apocalypse, and a group of super-rich individuals - billionaires, politicians, media moguls - find salvation in the ultra-modern bunker "Chimera". This underground complex, designed as a utopian city, is equipped with everything necessary for a comfortable life: from basketball courts and restaurants to zen gardens and spa centers. However, luxury and security turn out to be just an illusion. Cut off from the outside world, the characters not only face psychological pressure and paranoia, but also long-standing conflicts. Two influential families, linked by a tragic past, are forced to coexist in a closed space. Their old grudges and secrets gradually come to the surface, threatening to destroy the fragile world inside the "Chimera".
