Burt Lowell has been living as a recluse in an abandoned ghost town but someone puts a price on his head, and he wants to find out who, and why. Confronted by a gang of gunslicks, the trail leads to Rickard, a scheming ranch owner, but there is a more sinister figure behind him, the elusive railroad boss, Mossman. Riding for the rival Long Rail brand, Lowell sets off on a trail drive to Shoshone Flats where Mossman has opened a branch line. But where is he? The search for the truth becomes a quest for revenge. Somewhere down the tracks Lowell must find and confront Mossman on his own ground if he is to arrive at a final resolution.
