There's a single piece of land around Flagstone with water on it, and rail baron Morton aims to have it, knowing the new railroad will have to stop there. He sends his henchman Frank to scare the land's owner, McBain, but Frank kills him instead and pins it on a known bandit, Cheyenne. Meanwhile, a mysterious gunslinger with a score to settle and McBain's new wife Jill arrive in town.
