In a near-future metropolis, technology and capital are monopolized by a powerful few. A mysterious consortium runs a top-tier underground reality show called "Beast Game," catering to the wealthy elite's sick desire to watch and control others. The third season, "Liar's Tavern," takes place in secret aboard the enormous cruise ship Babel, from which there is no escape. The contestants are people deemed "failures" in real life or carefully selected targets of the consortium. The core game, "Liar's Tavern," is a card game built on psychological warfare, probability, and deception. It combines brutal eliminations with the drama of a reality show, livestreamed across the global dark web at the cost of real human lives. The total prize money reaches one hundred billion, but only the sole "last player standing" can leave alive with all the winnings. Those who lose face "social erasure" and physical elimination.
