Joel quickly takes a shine to this red stallion, and soon he, the horse, and Joel's dog Curly, become inseparable. Life is idyllic until Joel learns that his grandma, Aggie, must sell the ranch due to financial problems. But Joel has a plan to turn Red into a great racing horse to raise the money before the foreclosure deadline.
