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.

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.
