Marshal Dillon is trying to bring a suspected murderer back for trial (on foot)for killing a lawman friend of the Marshal's. He finds the man near a large sheep ranch run by an independent Australian immigrant named Tyson. Tyson wants to handle the prisoner in his own way for allegedly killing a few of Tyson's ranch hands. The Marshal enlists the help of a local doctor and Tyson's own daughter while acquiring horses. Ultimately Tyson and the Marshal meet face to face before returning to Dodge City.
