A woman, a computer, an invisible contact: this is where Marker's new film begins. Laura's job is to design a video game based on the battle of Okinawa, a tragedy little known in the West but which played a determining role in the outcome of World War II, in the postwar period, and even in our own day. But unlike classic strategy games, where the goal is to change the course of history, the aim of this game is to recreate the events of history exactly as they happened. Working on "Okinawa," Laura meets informers and actual witnesses of the battle (among them filmmaker Nagisa Oshima) on a mysterious Internet-like network. She gradually assembles pieces of the puzzle until one day they begin interfering with her life.
