The Six Shooter was a Western old-time radio program starring James Stewart as Britt Ponset, a wandering gunfighter and Texas plainsman. In "Gabriel Starbuck," Britt encounters an old friend who faces a difficult situation. Gabriel Starbuck is a 65-year-old sheriff who has served the town of Yellow Crest faithfully for years, but the townspeople believe he's getting too old to effectively perform his duties. The proud and stubborn Gabe refuses to admit his advancing years are affecting his ability to protect the town, creating tension within the community and putting Britt in the delicate position of trying to help his old friend while dealing with the practical concerns of effective law enforcement.
