Johnny Mack Brown is Steve McLain and undercover agent for Wells Fargo Company sent to end the criminal activities of a local gang which is controlled by Ace Pringle, the local saloon owner who is plotting to take control of the town with the assistance of the local sheriff and deputies.The story begins with Johnny falling for stagecoach passenger Suzanne Kaaren as Linda Forbes, daughter of the local judge.Pringle and the local sheriff continually attempt to frame or kill Johnny but he is always one step ahead. Many of the nefarious plans are lame and almost comedic but that was not the original intent. Don't expect great acting as the characters are predictable and the situations contrived.The ending is pure Happy Trails.Republic Productions distributed this Supreme Pictures film which was never meant to be more than a B-Western. If you like Johnny Mack Brown, you will enjoy this movie. Otherwise, there are many other B-Westerns of greater merit.
