Even enemies can find common ground.

John Wayne and Rock Hudson "set one another off handsomely" (Motion Picture Exhibitor) in a western so rugged, it "makes True Grit look avant-garde" Featuring "an excellent supporting cast" (The Hollywood Reporter) and tremendous scenes of sprawling action, The Undefeated delivers the one-two punch of Wayne and Hudson in a western of epic scale! In the tumultuous aftermath of the Civil War, Colonel John Henry Thomas (John Wayne) of the Union Army leads his heroic men to the Rio Grande to sell a herd of horses. Along the way, he crosses pats with h is former opponent, Confederate Colonel James Langdon (Rock Hudson), who is leading his troops to Mexico to fight for hire. Old tensions flare, but when new trouble threatens them both, the old enemies realise their only chance for survival demands that they trust one another...and fight side-by-side!
