During the Great Depression, everyone had to hold on to a dream to get through the darkest times, and Charles Howard (Jeff Bridges), a frustrated car manufacturer, was no exception. He bought a small racehorse named "Sea Biscuit" and recruited a group of people with the same dream, intending to enter the horse racing circle. The first person to discover Sea Biscuit's talent was trainer Tom Smith (Chris Cooper). He believed that although this horse was short and his legs were not very smart, it was full of stubbornness and stubbornness in its nature, which might make it the king of the horse racing circle. They found former boxing champion Red Pollard (Tobey Maguire) as Sea Biscuit's jockey, and the three of them and one horse found the direction of life again in their common journey.
