"Based on a radio teleplay starring James Stewart, Restless Gun follows the exploits of Vint Bonner (John Payne) a retired gunfighter and restless drifter who wander the Southwest in search of adventure. Preferring to find peaceful resolutions to the problems he faced, Bonner was often given no choice but to fight and his proficiency with a gun made him a fearsome opponent to those who dared cross him. Bonner carried around a special kit that would extend the range of his gun, this involved extensive assembly and became a novelty for the show and inspired Westerns that followed."
