IRS agent-turned-PI Mortimer Angel is relaxing in a hole-in-the-wall bar in a Reno casino when an attractive young girl hires him to find out who left her a cryptic message demanding a million dollars. At the girl’s house, Mort finds the body of missing rapper Jonnie Xenon --- Jo-X to his legions of fans --- hanging from the rafters with two bullet holes in him. Mort is shocked when he learns the identity of the girl’s father --- and even more shocked when the father hires him to investigate the murder.

Mort, being Mort, accumulates a few felonies as he follows the clues to Las Vegas. And along the way, he picks up an alluring young assistant who changes his life --- in every conceivable way.
