Tom loves running through cow fields with his best friend, Peggy, and his dog, Amos—especially when he's pretending to be his favorite radio hero, the Lone Ranger. But when Tom learns the nearby Fraser River is about to flood, he may have to become a real-life hero and help save his family's herd of dairy cows. This story is based on real events that happened in the farming community of Agassiz during the Fraser River flood of 1948.
