Zoe was the fastest runner at school and always dreamt of competing in the Olympic Games. But she's broken her leg very badly and the doctors say she may never run again! Now Zoe's been referred to the Harvest Hope project at City Farm, where kids facing difficulties are given space and support. She'll help to look after lots of animals who, she realizes, have needs of their own. These she meets kind-hearted Jack, Asha the chatterbox, and a beautiful retired racehorse names Swift. Can Swift and Zoe find a new dream together?
