Based on the book by Philip K. Dick, the film is set in a future in which the U.S. has lost out in the struggle against drugs. Within this context, policeman Fred (Keanu Reeves) is one of the many agents who have surrendered to addiction to a popular chemical substance that will split the personality of a user in two. Things become complicated when Fred's alter ego, a trafficker by the name of Bob is, in turn, hunted down by the faction of the police commandeered by Fred himself. The film was made with the same technique used in Waking Life (2001, selection for the 25th Mostra), a film also directed by Richard Linklater and winner of the Magic Lantern Prize at the 2001 Venice Film Festival in which the actors are filmed in scenes as per usual, subsequently made over with animation.
