When she wakes, she is alone in a deserted parallel world that resembles Yokohama. On her phone she finds a photo of herself that she has no memory of posting. Meanwhile a digital double called SHIORI has taken her place in the real world and is rising fast as a pop idol and influencer, while the real Shiori can only watch. Guided by Komori, a strange rabbit-man she meets there, she must find her way through an eerie cyber labyrinth to get back to her own life. The film blends horror and science fiction.
