Meet Helen and Hannah. They're identical twins - and mad about the animals on their Lake District farm!
A thoroughbred foal is born at a livery stables near Doveton - surprising everyone with her early arrival! Hannah and Helen only just get there in time to watch. Now she needs special care, and the twins are willing volunteers. Left in charge while her owner is away, Star springs another surprise on them by disappearing. Has she run away, or is it theft? The twins only have twenty-four hours to find out!
