Opening credits sequence (4 seasons; 124 x c.60-min episodes). The two Sherman brothers and a drifter, Jess Harper, come together to run a stagecoach stop for the Great Central Overland Mail Company after the Shermans' father, Matt, was murdered by a greedy land seeker. The Sherman parents are buried on the ranch. Not until near the end of the series was it revealed that Matt Sherman had been falsely accused during the American Civil War war of having aided the Confederates. When Jess Harper finds on Sherman ranch land the wreckage of a Union gold wagon stolen by Confederate raiders, Slim sets forth with the officer accused of helping the Confederates, portrayed by Frank Overton, and an Army major, the real culprit played by John Hoyt, to clear Matt Sherman's name. The gold dust in question had long ago been scattered by the wind.
