A year has passed since 12-year-old Georgie Stone had a serious horse-riding accident. She lost an eye, her horse and her country life. All she has left is a horse braid bracelet to remind her of her lost brumby, Magic.

Now that she's back at the cattle station, Georgie tries to overcome her fear of riding and prepare for the two-week cattle muster. But she's worried about the herd of wild brumbies led by the Ghost Horse, being hunted by a local horsewhipper, Goldburn. As the Ghost Horse begins to follow Georgie on the muster, the stallion is in extreme danger. Could the grey stallion be her old horse, Magic? How can she prove it before Goldburn captures him?
