Wilbur Hoolihan (Lou Costello) accidentally kills a hack horse owned by King O'Hara (Cecil Kellaway) and his daughter, Princess (Patsy O'Connor) by feeding it candy. In the hopes of raising enough money to replace it, he and his friend Grover Mockridge (Bud Abbott) visit a gambling establishment. They are successful in raising the money, but before they can purchase a new horse, a con man swindles them out of it.
