The debut appearance of Hopalong Cassidy, who acts as a courier from his employer to return $15,000/-
to an old friend. However, he has been seen withdrawing the money from the bank, and is trailed all the way to his destination, where the very man who is following him holds captive the rancher, now disabled, and his daughter, to whom the money is to be paid. Mad shenanigans follow, and plenty of good guys, bad guys, bullets, horses and Apache Indians find themselves in the mix.
