Ethan ventures into this perilous contest to find his brother Noah, who has been missing for four years. Sophia, an emergency‑room nurse, is forced to join to raise funds for her daughter’s surgery. As fatal rounds unfold‑‑Heartbeat, the Body Key, Crown Voting, True‑and‑False Debt and more‑‑players fight to survive between the rules and final reckoning.
