"Seabiscuit" recalls the squat and ugly racehorse that riveted the nation in the late 1930s. Interviewees include author Laura Hillenbrand ("Seabiscuit: An American Legend"), who charts the Cinderella story of this "equine catastrophe," as narrator Scott Glenn calls him, and his hard-luck jockey, Red Pollard, who kept getting hurt. But Seabiscuit won, often inspiringly and most notably in the 1940 Santa Anita Derby, in which both the horse and jockey were coming off injuries.
