There's a game based on lies and deception growing popular in Japan. The game is called 'Rabbit Doubt' and it is played on cellular phones. The premise of the game is that all of the players are rabbits in a colony, and one amongst them is randomly chosen to be a wolf that has infiltrated the group of rabbits. Every round, the wolf kills off a rabbit, and every round, the group tries to figure out which of the rabbits is actually a wolf in disguise. Sometimes the kids who play this game decide to meet up in person, and Yuu, Mitsuki, Rei, Hajime, Eiji, and Haruka have done just that. Unfortunately, while the group is enjoying themselves at a karaoke club, they are rendered unconscious and awake inside, what appears to be, an old, run down mental hospital. They soon discover someone among them has decided to take on the mantle of the wolf and has already killed once. As their situation grows more dire, their trust and camaraderie quickly dissolves and they begin to accuse one another, while the wolf continues to pick them off, one by one. Who is the wolf, and can they be stopped before everyone meets a very unpleasant end?
