No relation to the TV and radio series of the same name, Universal-International's Gunsmoke is a Technicolor vehicle for action star (and war hero)
Audie Murphy. Murphy plays a wandering hired gun who is commissioned to kill a rancher (
Paul Kelly). The film's conflict arises when the gunslinger befriends his would-be victim and comes to reject the attitudes of those who hired him. The fact that the gunman has fallen in love with the rancher's daughter (
Susan Cabot) may have something to do with his change of heart.
Audie Murphy mends his ways by the time Gunsmoke comes to a close, as if there was any doubt. ~ Hal Erickson, All Movie Guide
