The new owner of the Flying U Ranch, Margaret Whitmore ('Doris Weston' (qb), thinks her ranch foreman, "Chip" Bennett (
Johnny Mack Brown), is guilty of shooting bank president Wilson (
Henry Hall) and robbing the Ridge Bank. The real culprits are a gang of outlaws working with a band of enemy agents smuggling munitions on the shore line of a coast that borders the ranch.
