doubt

Doubt revolves around a fictional cell phone game called "Rabbit Doubt". The players are rabbits in a colony; one of these players is randomly chosen to act as a wolf infiltrating the group. Each round, the rabbits guess which is the wolf as the rabbits are eaten one-by-one until none are left.

Four players of the "Rabbit Doubt" game Yū Aikawa, Eiji Hoshi, Haruka Akechi, Rei Hazama and a non player Mitsuki Hōyama meet to relax together. During the day, the group is rendered unconscious. They awaken in an abandoned psychiatric hospital to meet Hajime Komaba, a player who did not appear at the meeting and find Rei crucified. The group finds Rei's cell phone and realizes they are playing a real-life game of "Rabbit Doubt". To survive, the wolf, the liar, must die.
