Hannah, Jade and Charlotte are mad about ponies and love riding. So when disaster strikes, they're the first to ride to the rescue... Hannah's on holiday with her mother - and her mother's new fiance, Frank. They're canoeing down the river while Hannah pony-treks alongside.

Riding full pelt through a fierce storm, she knows he is dependent on her for help - and it's a race against time to find it....
