Bank robber John Banner decides to go straight. Pitching up in the small town of Christian Flats, he offers to drive the stagecoach to Laramie, despite the last one returning with the driver and passengers killed by the Cheyenne. On board is a mix of the good and the bad, including bank teller John Carter, suspected of one of Banner's robberies, showgirl Amy Clarke and Native American-loving Senator Blakely.
