Comin' Round the Mountain is a 1936 Western film directed by Mack V. Wright and starring Gene Autry, Ann Rutherford, and Smiley Burnette.

In addition to the mail, the saddlebags contain money being sent to ranch owner Dolores Moreno (Ann Rutherford) who desperately needs the funds to save her land from being sold for back taxes.

After selling her cattle to raise the necessary money for the taxes, Dolores plans to breed horses, using a wild stallion named El Diablo to start a good bloodline.

She doesn't know that it was Ford who sent his henchmen, Slim and Butch, to steal her money from the Pony Express rider so she would be forced to marry him and he could gain control of her ranch.

After the race, Gene exposes Ford's trick, and Frog reveals that he found Butch on the trail with Dolores' money.
