The Sound Of A Drum

Another feature-length episode of the 1960s Western series set in the town of Cimarron. In this instalment, Sergeant Clayton Tyce (Steve Forrest) is found drinking in a Cimarron bar while on duty, and is offered the painful choice of an honourable discharge or a court-martial. Meanwhile, Marshal Jim Crown (Stuart Whitman) is after a gang of some cattle rustlers with an uncanny knack of avoiding army patrols.

Could someone be tipping them off?
