In the world of the film, the 2020 Tokyo Olympics were cancelled due to corruption by the minister in charge and there has been an attempted spraying of poisonous gas by a new religion. In the shadow of these two incidents, the murder of a convenience store owner has drawn a limited response from police and press but a suspect in the killing has been found: high school girl Sanagi, a loner who had an exchange with the victim's young son Shiro. The axis of the film is her questioning by a psychiatrist and a detective but it won’t be easy since she is suffering from multiple personality disorder and her personalities each emerge at random to recollect what happened from their respective perspectives.
