When Doc suffers a mild heart attack, Matt Dillon must find a young frontier doctor to help the aging man with his work load. Dr. Jerome Gentry seems to fit the bill. He quickly becomes popular with the townspeople after mending a few patients--and a little too popular with the ladies--single and otherwise. But when a gang of outlaws rob the local bank, leaving wounded behind, Dr. Gentry is nowhere to be found. Was he in on their plot, or is he in a whole lot of trouble...?
