This hilarious oater finds Jesse Heywood (Don Knotts) as a Philadelphia dentist who leaves his home to open a new practice on the western frontier. The hapless dentist is saved by the expert gun handling of Penny (Barbara Rhoades), a reformed bandit trying to earn a pardon by intercepting gun shipments to hostile Indians. After several more situations in which Penny saves the nervous newcomer, Jesse believes he has exceptional firearms prowess and believes himself to be a hero. Comedy ensues when the jumpy Jesse faces a bevy of bad men and nervously clutches a six shooter with a very unsteady hand. Penny has to help the pseudo-hero out of even more trouble before they can ride off together into the sunset.
