Something's stirring Alice up, and she's usually such a placid dog. When the Green family follow her she leads them to an abandoned foal, and only Eddy the cocky seems to know where he comes from: a brumby herd led by the magnificent thoroughbred stallion Rise and Shine. Meg calls him Sunshine. With a sire like Rise and Shine, Sunshine could become a famous racehorse and win the Melbourne Cup, but would that make him happy? And do Meg and Mike want him to be a champion anyway - or just a horse, of course, and another of their many four-legged friends?
