An older man, Murdoch (Franchot Tone), and his young grandson Willie (Billy Mumy), arrive at Medicine Bow on foot. Much to the Virginian's chagrin, Trampas feels sorry for Murdoch and offers him a job at Shiloh. Murdoch's ineptitude causes several problems, and he begins to resent his grandson's admiration for top cowboy Trampas. In the end, however, Murdoch more than proves his worth and gains the admiration of all, including his grandson.
