Sheriff McKeever is killed when his scheme to restore his gunslinging youth fails, leaving deputy Bronco to discover who was behind the backfire.

Bronco unwittingly introduces a demure con artist to a rich man.

Bronco hires refugees from the fallen Maximillian empire, but has to contend with bandits who are convinced the mother and son know what happened to $5 million in missing gold.
