Blue Montana Skies is a 1939 American Western film directed by B. Reeves Eason and starring Gene Autry, Smiley Burnette, and June Storey.
Based on a story by Norman S. Hall and Paul Franklin, the film is about a singing cowboy who goes up against a gang of fur smugglers operating near the Canada–United States border.
After discovering the body of their murdered friend and his final cryptic clue, Gene and Frog ride to the nearby HH ranch, which is owned by Dorothy Hamilton (June Storey) and her partner, Hendricks (Harry Woods).
Suspicious of Hendricks, Gene and Frog stampede their cattle into the HH herd as an excuse to spend time at the ranch and investigate.
After the smugglers leave, Frog escapes from the storeroom and organizes a rescue party to search for Gene and his captors.
