In early-1970s Las Vegas, low-level mobster Sam "Ace" Rothstein gets tapped by his bosses to head the Tangiers Casino. At first, he's a great success in the job, but over the years, problems with his loose-cannon enforcer Nicky Santoro, his ex-hustler wife Ginger, her con-artist ex Lester Diamond and a handful of corrupt politicians put Sam in ever-increasing danger.
A ruthless killer (Gary Hudson), hell bent for revenge, escapes prison and vows to kill the Texas Ranger (Sam Jones) who sent him there. With the aid of his two brothers, he set off on an explosive journey to make his tormentor pay the ultimate price, a slow tortuous death.
