Marshals Virgil Cole and Everett Hitch haven't seen much trouble of late. But with the arrival of a young widow from San Francisco, the lawmen are about to be put to the test. Rose McMaster, the feisty daughter of Virgil's half-brother, ushers in a whole new unsuspected brand of trouble; her husband, Frank is a young and successful attorney but as business problems escalate, he's found dead - an apparent suicide. Just as Rose is moving on, she receives a plea to leave San Francisco immediately for her safety, but no sooner does she step off the train in Appaloosa than trouble arises.
