Nick Barca is a former cop in debt to a notorious gangster. He's offered a one-time deal to even the score and save his family. All he has to do is kill a maverick Vegas cop at his own retirement party. Once in Sin City, he encounters Sable, a former stripper he had an affair with years earlier, and D-Man, a cocky loner who appears to be gunning for the same target. Barca will need more than lady luck to survive.
