Post-Civil War Texas is a hell of a rough place. And for a man wearing a kilt, it is even rougher. Colin Farquharson insists on retaining his native Scottish dress but to do so unarmed on the Texas frontier could get him killed. At least it provides a distraction for the bandits attempting to rob the stage he's on and a distraction is all his fellow passenger, the Ysabel Kid, needs.
Unfortunately the leader of the bandits is killed in the process and his brothers blame Colin and come looking for him. If he's going to stay alive long enough to impress mustanger's daughter Jeanie Schell, Colin will have to learn to use a gun and he'll find no better teachers than the fighting men of the newly formed floating outfit.
