The filmmaking trio behind the hit sci-fi sequel Terminator 3: Rise of the Machines re-team to explore a future in which humans live in isolation while only communicating with their fellow man through robots that serve as social surrogates and are better-looking versions of their human counterparts. Bruce Willis stars as an FBI agent who enlists the aid of his own surrogate to investigate the murder of the genius college student who invented the surrogates. As the case grows more complicated, however, the withdrawn detective discovers that in order to actually catch the killer he will have to venture outside the safety of his own home for the first time in many years, and enlists the aid of another agent (Radha Mitchell) in tracking his target down. Jonathan Mostow directs co-screenwriters Michael Ferris and John Brancato's adaptation of the graphic novel by author Robert Venditti and illustrator Brett Weldele.
