Beth Raymer leaves her dancing job at a Florida strip club to become a Las Vegas cocktail waitress. Not exactly an ideal career choice, but her borderline-ditzy personality doesn't give her many options. In walks Dink, a professional sports bettor who sees through her bubbly exterior and offers her a job placing wagers all over town to gain an advantage over the casinos. Her surprisingly impeccable mind for numbers soon cements her status as Dink's good-luck charm, until his gorgeous-but-frigid wife, Tulip, starts to get jealous.
