 Traveling west, former peace officer Frame Johnson and his three friends arrive in Tombstone, a lawless town controlled by the three Northrup brothers. Preceded by his reputation, the town Council tries to get him to take the job of Marshal. He says he will not wear a badge again but seeing the ruthless Northrup murders he accepts. After a killing on both sides, although outnumbered, Johnson and his two remaing friends head to the OK Corral for a shoot out with the two remaining Northrups and their men.
