Phillip (Slick) Roth (Tony Curtis), is a wealthy Las Vegas Hotel Casino owner who is close friends with detective Dan Tanna. Tanna not only works casino scam and potential criminal cases for Roth, he also spends free time with him. Roth is a wealthy man, but he remembers the stressful and tough times before he was wealthy, and he often exhibits a earthy and self deprecating sense of humor in his dealings with Tanna, casino guests, showgirls, and the employees on his hotel staff.
