After putting on a virtual reality headset, a human becomes trapped in a circus-themed digital universe, where she assumes the avatar of a jester and meets five other people who share her situation, unable to remember their names and details of their pasts. The ringleader of the circus, an artificial intelligence called Caine who controls the digital world, is dedicated to offering them adventures to prevent them from going crazy and assigns the woman the new name "Pomni." The six now fight to maintain their sanity in an unnatural and claustrophobic digital world, all while Pomni searches for a way out that is difficult to reach.
