Set on a world populated entirely by robots, this is the story of a young genius, Rodney (Ewan McGregor), who wants to make robots capable of making the world a better place, but he finds his dream challenged by a corporate tyrant and a master inventor, Big Weld (Mel Brooks), while also being seduced by a sexy corporate robot, Cappy (Halle Berry).
After their adoptive mother is murdered during a grocery store hold-up, the Mercer brothers--hotheaded Bobby, hard-edged Angel, family man and businessman Jeremiah, and hard rocking Jack--reunite to take the matter of her death into their own hands. As they track down the killer, they quickly realize that their old ways of doing business have new consequences.
