In an attempt to save their home in England, Roger Calverton (Ronald Sinclair) and his uncle (C. Aubrey Smith) enter their racehorse Pookah in a high-stakes American race. While staying at a local boarding house, they meet Cricket (Judy Garland), the owner's niece who dreams of becoming an actress, and Tim (Mickey Rooney), a hotshot jockey whom they persuade to ride Pookah to victory. When Tim makes a fateful decision that could cost them everything, Cricket steps in to save the day.
