Nick Wild (Jason Statham) is a recovering gambling addict who takes odd jobs in Las Vegas as a “chaperone” (his version of a bodyguard) to support his addiction. After helping a client impress a woman (Sofia Vergara), he accepts a proposition from meek self-made millionaire Cyrus Kinnick (Michael Angarano) to show him around Vegas and provide him with protection while he gambles.
While eating at a diner, Nick’s waitress friend Roxy (Anne Heche) hands him a message from a woman he knows, Holly (Dominik Garcia-Lorido), who wants him to stop by her house. Holly, a professional escort, explains she had a date the previous night at the Golden Nugget. Afterward, she was brutally raped and beaten by three unknown men in their hotel room. Holly asks Nick to find out who they are so that she can sue them, though unbeknownst to Nick, she plans to take revenge.
Nick discovers that the man responsible for raping Holly is Danny DeMarco (Milo Ventimiglia), a gangster. DeMarco had his two thugs dump her in a hospital car park. Nick goes to the hotel to confront DeMarco, disguised as someone sent by another criminal. A confrontation develops but Nick defends himself, overpowering DeMarco and his men, who are tied up as Nick calls Holly. In the room, Holly contemplates castrating DeMarco, who breaks down and begs her forgiveness, Holly decides to take $50,000 from DeMarco’s desk and leave.
