Gil Favor is trail boss of a continuous cattle drive; he is assisted by Rowdy Yates. The crew runs into characters and adventures along the way.

The last cattle drive to Sedalia having been completed, Favor writes to his crew to meet him in Rio Salado to start a new drive. At that town, Rowdy accidentally encounters his drunkard, near-do-well father (Dan) who had deserted the family many years ago. To get a grubstake to start over with Rowdy, Dan disgraces himself by shooting in the back Antonio Marcos, a famous, well-liked quasi-revolutionary outlaw with a $5000 price on his head. That killing sickens everyone including an important rancher who now refuses to turn his herd over to Favor and the crew. Disappointed, and with the crew penniless, Favor has to forge alternative plans to gather a new herd. Season premiere. Written by chipe
