In the two previous series, Bret Maverick had been a solitary rounder who travels from riverboat to saloon looking for high-stakes games. In this series, Maverick has settled down in Sweetwater, Arizona Territory, where he owns a ranch and is co-owner of the town's saloon. However, he is still always on the lookout for his next big score, and continues to gamble and practice various con games whenever the chance arises. The series was developed by Gordon Dawson, and produced by Garner's company Cherokee Productions in association with Warner Bros. Television.
