An outlaw gang led by an Irish expatriate takes advantage of a Grand Duke fondness for pretty young ladies and kidnaps the Russian nobleman while he is visiting Cimarron City as part of his grand tour of the United States. Matt Rockford attempts to impersonate the duke to lure the gang into a trap not realizing that the Irishman is an expert swordsman when the outlaw challenges him to a duel.
