Tennessee Walker, a notorious gunman drifting through Texas, happens upon a tense conflict between landowners. He knows little of the Mormon ways, but cattle are being stolen, and Ruth—a pretty widow who understands nothing of guns or the term fighting wages—begs him to stay.

Will this unlikely collaboration triumph, or will all that Ruth possess be lost?
