When part of Oklahoma Territory becomes officially part of the U.S., Vance Cordrell is forced to deal with some of the most infamous outlaws of the Old West.
The success of 1947's Badman's Territory prompted RKO Radio to assemble another "outlaw rally," Return of the Badmen. Randolph Scott plays US marshal Vance, assigned to rid the Oklahoma Territory of outlaws. This proves to be quite a challenge, inasmuch as virtually every frontier bad guy has converged upon the territory. Led by the surly Sundance Kid (Robert Ryan), the rogue's gallery includes the Younger Brothers (Steve Brodie, Richard Powers, Robert Bray), the Daltons (Lex Barker, Walter Reed, Michael Harvey) and Billy the Kid (Dean White). For all the formidable villainy, the film's most fascinating conflict develops between the two heroines: feisty Cheyenne (Anne Jeffreys) and prim 'n' proper Madge Allen (Jacqueline White).
