Barbie™ and her sisters set off on a Swiss adventure to the majestic Alps, where they’re excited to spend the summer at a fun-filled riding academy! Barbie™ can't wait to find a new horse to bring back to Malibu. Stacie™ is super excited to prove she’s an amazing equestrian. All Chelsea™ wants to do is ride the big horses, and Skipper™…well let's just say she’s more interested in writing about the great outdoors than experiencing it. The sisters' vacation gets off to a rocky start, but when Barbie™ discovers a mysterious wild horse in the woods, their visit becomes truly magical.
