Issie and Blaze were hot favourites to win the Chevalier Point Pony Club dressage competition, but now they have to spend the summer on her aunt's farm instead! When Issie finds out Blaze can go with her - and she'll be helping to train horses for the movies - things start to look up. During her stay Issie overhears a conversation about plans to cull a group of wild ponies, and she is determined to find a way to save them, espcially the beautiful stallion Destiny, who bears a striking resemblance to her aunt's favourite stallion Avignon. It's lucky that Issie's made friends with her aunt's handsome farm manager, and can call on her pony-club friends, because she is going to need all the help she can get...
