Dapple the fawn gets carried away exploring the park near the woods where he lives with his mother, Fern. But when Fern comes to find him, she gets tangled in a wire. Can Dapple find someone to help set her free? Olive the otter loves playing in the river near her home. But when she disobeys her mother and strays out after a rainstorm, Olive gets washed far downstream and lands on the bank in a city park. How will she ever find her way home? Luckily for Dapple and Olive, Hassan and his mum, a wildlife ranger, live close to the park and can help both little animals back to safety.
