Gunfighter Chase Bucklin agrees to help his recently widowed sister-in-law trail a herd of cattle from southwest Texas to the railhead at Ellsworth, Kansas, but first he must rescue his kidnapped nephews. Then armed with a six-gun on his hip, and a Bible in his saddlebag, Bucklin and his partner Yancy Andersen deal with desperados, Indians, violent storms and a flooding river. Old enemies, along with some new ones he's made on the long trail ride, are waiting for Bucklin when the herd arrives in Ellsworth. The streets of the wickedest cow town in the west are alive with gunfire, as a dramatic showdown interrupts a quiet Sunday morning. The lives of those that survive will be forever changed.
