After the ordeal in the last episode, Ash and co. continue training and are joined by Prof. Birch. May is so happy that her Silcoon will soon evolve. Elsewhere Jessie is still in denial of the fact that her "Silcoon" is really a Cascoon. After a fierce battle, Silcoon evolves into Beautifly and blows away Team Rocket with a Gust attack. How will Jessie get her "Silcoon" to evolve and how will she take it if it doesn't evolve into what she wanted?

As Ash prepares for his rematch with Brawly, he, May, Max and Brock meet a Battle Girl by the name of Shauna, whose reason for battling was to prove she was better than Ash. During their battle Brock noticed that while Ash's training was paying off Shauna battled like Ash used to. Just as the match was about to be decided Brawly appears with some mondo bad news: A hurricane was approaching which could wipe out the beach. Can our heroes manage to weather the storm, and why is Shauna so nervous around Brawly?
