Doubt

Rabbit Doubt-a mobile phone game-has taken Japan by storm. In it, players are rabbits who must uncover the wolf in rabbit's clothing before falling prey to its mistrust-sowing wiles...as well as its teeth. When a group of teen players decides to meet offline for fun, the last thing they expect is to lose consciousness and wake up trapped in an abandoned building, mysterious bar codes tattooed on their bodies, and a corpse strung up in front of them. To stay alive and find a way out, they have but one option-to sniff out the lying wolf in their midst. Will these virtual acquaintances be able to pull it together in the real world and figure out what's going on in time to avoid ending up as the wolf's dinner?
