Veteran western director Burt Kennedy wrote the screenplay for this tale, based on the novel Who Rides with Wyatt? and also released under the title Who Rides with Kane? Robert Mitchum, who sings the title song, stars as Ben Kane, an ex-sheriff hunting for Frank Boone (John Anderson), the man who killed his son. He enlists the aid of Billy Young (Robert Walker), a hired gun who was abandoned by his fleeing partner Jesse Boone (David Carradine) after they killed a Mexican general. Kane becomes marshal of Lordsburg and falls in love with Lily Beloit (Angie Dickinson), a dance hall girl. John Behan (Jack Kelly) and Jesse Boone try to kill Kane, but Lily warns him of the plot in time. Kane arrests Jesse Boone, and when Kane learns that his captive is the son of his son's killer, he uses him as bait in a plan to catch Frank Boone.
