Robert Colbert makes his first appearance as Brent Maverick, yet another cousin of frontier gambler Bart Maverick Jack Kelly) (Colbert sports the same costume worn by former series regular James Garner, a rather blatant move by Warner Bros. to create a "new" Bret Maverick). Riding into the town of Sunburst along with Bart, Brent is immediately thrown in jail--merely for owning the deck of cards used in a poker game. It appears on surface that Sunburst is a "temperance" town, where gambling and gunplay is strictly outlawed, and all the saloons close at sundown. But in truth, the town fathers have gone out of their way to make strangers feel unwelcome in order to to cover up a crime committed 20 years earlier--and they're willing to commit murder to make certain their dirty little secret is never revealed.
