Animal Haven is a temporary home for all sorts of Australian wildlife, although there are a few permanent residents as well, like Oscar the owl, Fur Bag the possum, Cinnamon the koala and Alice the labrador. Meg and Mike live there, too, and they work so hard to help their parents rescue and look after the animals that the locals at Jeff's Creek have nicknamed them the Aussie Angels.
Wild brumbies live quite a long way to the north of Animal Haven so the Angels are surprised to see a magnificent stallion suddenly rear up on the headland and charge off into the bush. With the help of Eddy the cocky and Alice the labrador, the Angels follow his trail and find a mare who is having trouble giving birth to her foal.
Uncle Pete the vet arrives in time to save the foal but not the mare, so there's another needy orphan to feed at Animal Haven. But how will Carol the camel feel about a foal nuzzling up to her as its substitute mum? And Midnight's no ordinary foal: Uncle Pete says he's obviously a thoroughbred and that he could be a Melbourne Cup champion . . .
