Former big-city detective John McBride is an easygoing man - until people rub him the wrong way. So he's less than please when he sees three hanged men outside the town of Rest and Be Thankful, and the local lawman warns him to behave if he doesn't want to end up swinging right beside them. Driven by the plight of the terrified citizenry - one beautiful woman in particular - McBride vows to take on the fast-gun marshal, and evil mayor and his cruel son, and a small army of hired gunmen. With the help of a mysterious white-haired preacher. McBride will give the townsfolk reason to be thankful - and their vicious tormentors eternal rest in hell.
