The Big Valley S01E02 - Forty Rifles

While preparing for a major cattle drive bunching the Barkley's herd with those of other ranchers, Heath has major difficulties being accepted as a Barkley, especially by the ranch hands. Then when Nick's former commander in the war comes to visit, Heath is suspicious of him, and with good reason. He is there to cause trouble and steal the herd!! Nick ends up getting shot while on the drive and has to be taken to town, leaving Heath in charge of the drive.
