When Tony Valentine, a master at catching casino cheaters, jets to Las Vegas to look for his missing son, he lands in the middle of a dangerous turf war between rival casinos. Valentine's longtime pal then taps him to figure out how an amateur won $25,000 at his blackjack tables. But the job is full of land mines. For starters, the suspect bears a strong resemblance to his late wife. Upping the ante, a dead stripper is found with Valentine's calling card - and her grief-stricken policeman boyfriend is vowing revenge.

Yet in a city where barracudas wear pinstripes, and reality and illusion shift depending on the neon light, a greater threat maneuvers through the streets: an all-new breed of criminal with an agenda propelled by fury that will shake not only Valentine, but the city of Las Vegas itself.
