Nick Wild 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, he accepts a proposition from a young man, Cyrus Kinnick, to show him around Vegas and provide protection while he gambles.
While eating at a diner, Nick’s waitress friend Roxy hands him a message from a woman he knows, Holly, 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.
Nick discovers that the man responsible for raping Holly is Danny DeMarco, a gangster, who had two of his thugs dump her in a hospital car park. Nick goes to the hotel to confront DeMarco and a confrontation develops, resulting in Nick overpowering DeMarco and his men, who are tied up. Nick calls Holly, who contemplates castrating DeMarco, who then breaks down and begs her forgiveness. Holly decides to just take the $100,000 from DeMarco’s desk and leaves.
Holly splits the money with Nick and leaves Las Vegas. Nick takes Cyrus to a casino and whilst playing blackjack with dealer friend Cassandra, Nick goes on a huge winning streak with the next dealer, amassing over a half a million dollars. But when he goes to the cashier, he has a sudden anxiety attack and decides to keep on gambling, eventually losing all his winnings (as well as his original $100,000) on a single blackjack bet with Cassandra. The next morning, Cyrus, revealed to be a self-made millionaire, wants Nick to mentor him on being brave, but Nick declines. At the bar, DeMarco’s men arrive to deliver Nick to DeMarco, but Nick fends them off.
