Inspired by a true story, "Moondance Alexander" follows a spirited teen named Moondance (Kay Panabaker) living with her eccentric mother (Lori Loughlin). Moondance is faced with another uneventful summer until she discovers a lost pinto pony named Checkers who has jumped out of his paddock. Although she returns the horse to his rightful owner, the gruff and mysterious Dante Longpre (Don Johnson), Moondance is convinced that Checkers is a champion jumper in disguise and is determined to help him realize his full potential. She manages to talk Dante into training her and Checkers for the Bow Valley Classic and despite the criticism of her nemesis, Fiona (Sahsa Cohen); discovers that perseverance, loyalty and individuality can land you in the winner's circle.
