From the very beginning, the people of Pony, Montana had suspicions about Sam Stop - he didn't dress like or act like a banker. But in time they came to respect and trust the reclusive founder of Pony's local bank and it soon became the main depository for the assets of the Pony Consolidated Mining Company. Then one day two eastern financiers appear in town. The two bankers decide to call in their loans to mine owner Ben Waldorf prematurely. And it soon becomes tragically clear that they have the methods and the manpower to do so. Stop desperately tries to arrange re-financing for Waldorf, but his attempts are futile. The situation worsens until finally the town is in a state of siege. Then it becomes time for Stop to show the town his true colours.
