The outlaws' first mistake was shooting the dog. That dog belonged to Rhett Coulter and he wasn't a man to mess with, as Lorne Roberts and his gang of gunslicks would soon discover. Meanwhile, Coulter's friend's ranch, the Block H, is burned down and his woman barely escapes with her life. Now he has another reason to want to put Roberts out of business, quite apart from the little matter of his hoard of stolen bullion. As Coulter fights against overwhelming odds, events hurtle along like a runaway stagecoach towards the final, blistering showdown.
