The movie begins with Su and his classmates playing a "date game" with a Daruma doll, where the doll kills anyone who moves or fails to complete a task. Su and his friend Ishii are the only survivors of the game and soon discover that the same game is being played in all the classrooms. They try to escape and find help but are unable to call the police or break the glass to escape.
Su and Ishii meet other survivors, including a girl named Ishika, and they form an alliance to survive the games. They are forced to play a series of deadly games, including a basketball game where they must throw a ball into a hoop while avoiding a giant cat, and a singing game where they must identify the correct doll.
Throughout the games, Su and his friends use their wits and resourcefulness to survive, but not everyone makes it. In the final game, Su and Amaya are the only survivors, and they are forced to play a game of cat and mouse with each other. Su ultimately sacrifices himself to save his friends, but surprisingly, he does not die.
The dolls that have been overseeing the games reveal that Su and Amaya are the winners, but only because they had the power and courage to survive. The other survivors are killed, and Su and Amaya are declared the "sons of God". The movie ends with Su and Amaya being brought out of the game, with Su feeling sad and Amaya feeling happy about their victory.
