 Ken saves Joan Peters (June Gale) from her runaway horse. He learns that she is trying to save her brother, Johnny (Harry Ernest), from an outlaw gang that are taking him to their hideout. Johnny, a clerk in the express office has huge gambling debts to gang leader "Bull" Lanson (Harry Woods) and they are trying to force him to tell when a money shipment is due. Ken and Joan arrive at the hideout, whe Ken poses as "Lightnin " Smith, a border gunman, and Joan poses as her fiancee. Johnny has been wounded and Lanson sends for and forces Doctor Brownlee (Lafe McKee) to take care of the boy. Ken tells Lanson that the money will be at the office that night, and gets word through the Doctor to Sheriff Sam (Jack Rockwell) to have a heavy guard on the office. Ken has to accompany the gang, and the Sheriff and his deputies engage them in a raging gun fight. Henchman Lem (Bob Kortman), who rightfully suspects that Ken is not whom he pretends to be, knocks Ken out with a gun. Lanson heads for the hideout with the money while his men cover his getaway, with Ken, actually a U. S. Marshal detailed to the district, in pursuit. Ken finds, he thinks, Lanson alone at the hideout but the real "Lightnin   Smith (Frank Hagney) has shown up. They ambush Ken and are about to kill him. Prior to this, Ken and a couple of musician groups sing and saw away (in the original unedited release at least) at "Red River Valley", "Thundering Hoofs", "Boots and Saddles" and "Our Old 45 s".
