Sixteen talented high school students regain consciousness inside a fortified academy with no memory of how they arrived, each discovering they possess a singular extraordinary gift—pianist Kaede Akamatsu and detective Shuichi Saihara among them. A sadistic mechanical bear calling itself Monokuma emerges to lay down the rules of an inescapable game: freedom comes only to those who successfully murder a peer and deceive their classmates during a subsequent trial, while exposure means execution. As the students grapple with the horrifying proposition and the academy's suffocating confines close in, desperation begins to chip away at their resolve, transforming the deadly competition into an inevitable descent into violence and betrayal.
