Real Steal takes place in the near-future, where robots have taken the place of humans in the sport of boxing. Charlie Kenton is a former fighter who now makes a living controlling these robots in freelance matches all across America. After losing yet another match and another robot, Charlie needs cash to buy a new robot, so that he can win enough money to pay off his increasingly violent creditors. Charlie receives a court summons forcing him to travel to New York to release custody of his 11 year-old-son Max by a former girl-friend, who he has never met, to her rich sister and husband. Seeing a way of financing his next robot, Charlie cons fifty grand out of the husband before signing over the boy. However, before they take custody of Max, Charlie must take care of Max for the summer, while the rich couple vacation in Europe.
Charlie uses his money to buy a former “champ” robot and is about to leave Max behind, but the stubborn Max insists on coming along to the fight. Charlie gets a headline fight, but his cockiness in the bout costs him both the robot and a beating at the hands of his creditors. Looking to steal spare parts to fix his robot, Charlie and Max break into a junk yard and accidentally stumble on an abandoned sparing robot, which Max insists on bringing back with them to repair. With the help of Charlie’s girlfriend Bailey, they repair the old sparing robot, which Max dubs Atom. While Charlie is off trying to find the parts to fix his damaged champion robot, Max uses the vocal command parts from it to control Atom. Soon, Max has Atom up and running and discovers that Atom has a shadow...
