Based on an adult social deduction game conceptualized by Dimitry Davidoff in 1986, this horror mystery film revolves around a deadly challenge. Twelve strangers, each abducted, are forced to participate in a sinister game where they must vote to eliminate one among them. During the night, the concealed "werewolves" among the group emerge to mercilessly slaughter a fellow "villager." This cycle of day and night continues until one side emerges victorious, revealing the dark secrets and survival instincts of the participants.
