Flesh and the Spur is a gritty Wild West adventure through murder, love, and gun fights. Regular John Wayne costar John Agar takes the helm in this rough and tumble affair. To lighten things up a bit, Hollywood stunner Marla English (Rear Window) is the leading lady. Agar is a cowboy whose twin brother has been murdered. Enraged, Agar is out for revenge, and finds gunfighter Mike Connors along the way to help him. As the big showdown with the killer looms, Agar must find a way to clear up his messy life so that he can ride off into the sunset.
