Poppy is thrilled that her best friend Sarah is finally coming to visit Starlight Stables. She is sure that Sarah will love it as much as she does - especially Poppy's beautiful pony, Crystal, and her horse-mad friends, fiery Milly and sweet Katie. But it soon becomes clear that Sarah doesn't share Poppy's love of horses and riding - in fact, she's more interested in helping Poppy's uncle with some bushfire-injured animals. When a bushfire erupts nearby, Poppy finds herself fighting not only to save her friendship but also to save her beloved Starlight Stables. Will she lose everything she loves?
