Steve Cannon, private detective, must walk a thin line between the mob and the cops in 1960's Las Vegas. When a tourist goes missing, Steve must find out what the man's sister is hiding and why a highly placed mob boss is protecting him. The bad news is that Steve is sleeping with the mobster's wife and when the hood goes missing, the law starts looking in his direction for suspects. The worse news is that the mob boss has hired a maniac killer to silence Steve forever.
