This is the story of two young animals forced to grow up fast. In Africa's savannah a baby elephant-shrew learns how speed is the secret to survival amongst the largest animals on earth and in America a young grasshopper mouse confronts the Wild West's deadliest creatures to stake a claim of his own.
