Dressed as rodeo clowns, two men rob a rodeo. Cannon is summoned to figure out what's going on, after authorities spend six weeks and come up with nothing.

Toby Hauser is a compulsive gambler who is $200,000 in debt to Ben Logan (who runs local illegal gaming operations). The bill is due and Hauser has about $5000; they threaten to come after Hauser's wife Cathy if payment isn't made. Cathy, sensing one of them will be hurt, calls in Cannon to help.

A girl's suspicious death brings Cannon to Texas.
