Melba is a Californian trailer-park girl who is told to look for three kings by a phone psychic, and when she meets three guys - Trent, Brad and Joel traveling to Las Vegas, she decides they are those kings and joins them on their trip.
In early-1970s Las Vegas, 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.
