With the Silver Conference only three months away, Ash decides to do some hardcore training for it. But before that, he, Brock and Misty head back to New Bark Town. However, they notice the ocean and a sign for a synchronized swimming class, run by a boy named Dorian, who is also the unofficial leader of the newly christened Coastline Gym. Dorian had a thing for Misty's sisters and thinks Misty is a loser. (Obviously, they never told him about what Misty can REALLY do.) Can Misty prove Dorian wrong, and what kind of synchronized swimming class has no female instructors or performers in it?
