Clay Parker and his cohorts are what is left of the once-infamous Tulley gang. They have waited five years to get the money they stole from a bank, which they believe has been hidden by one of their own - and he has just been released from prison. Now Hugh Donahoe is meeting up with his daughter Mena in the town of Battle Mountain. When his old gang mates confront him, he is killed. The money is not found, however, and the gang suspects that Mena has hidden it in a trunk, which is being carried by Glen Maddox and his mule freighters across the Nevada plains and on its way to Oregon. Parker devises a plan to attack the mule train to get to the stolen money. But Parker is unprepared for the grit of Glen Maddox and his freighters.
