Guns don't stay in their holsters long when vigilantes Wyatt Earp and Doc Holliday meet outlaws in the Wild West. With the dust settled at the OK Corral the notorious Clanton brothers unleash their revenge. One by one they gun down Wyatt Earp's brothers - but they won't have the last shot. Using his US Marshal's badge as his authority and Doc Holliday (Jason Robards) as his deputized right-hand man Earp (James Garner) begins a zealous pursuit of vengeance that the West will never forget.
