The film tells the story of a computer scientist working on a secret international project that attempts to turn humans into digital mediums. A failed attempt to use his son as a test case results in the young man becoming lost in cyberspace, a spectre haunting the past, present and future worlds that continuously interact and overlap throughout the film. By mining the history of her immediate context, Cao Fei takes us on a ‘retro-futurist’ journey that goes beyond chronological time and hovers between reality and fantasy.
