It was remade in 1947 as Killer McCoy, featuring Mickey Rooney in the title role.

The supporting cast for the 1938 version features Edward Arnold, Frank Morgan, Lionel Stander, and Jane Wyman.

While training, Tommy meets and falls in love with Cain's daughter Sheila.

However, "Pug" Walsh, a traitorous associate of Cain's, sends Tommy a bouquet of flowers with a message and Sheila's driving license (which erroneously spells her first name) indicating that she and the elder McCoy have been kidnapped.

However, while he is distracted by the radio broadcast of the fight, one of the men shoots him; he fires back, and all three are killed.
