When the showman Fergal O'Brien and his assistant Randolph McDougal help a damsel in distress who has been attacked by the bandit Van Romalli, she repays their kindness by riding off with their display of authentic historical memorabilia.

So somehow Fergal has to find a way to earn a living, and an opportunity arrives when Jim Broughton sells him an attraction called the Treasure of Saint Woody. All is not as it seems. Jim is really a US marshal and the only person he wants him to attract is Van Romalli. Blissfully unaware he is being used as bait, Fergal is starting to rebuild his fortunes when Ezekiel T. Montgomery rides into town to promote the wondrous maiden voyage of a flying wagon.

Faced with a seemingly unbeatable competitor, Fergal tries to solve all his problems with a reckless wager, which leaves him facing his greatest ever challenge. He has twenty-four hours to learn how to fly or he'll lose everything!
