Ash and his friends arrive at the beautiful land of Michina. Little did they expect to once again be found in a conflict between Dialga, Palkia, and Giratina. They are saved by a young woman called Sheena, who can communicate with a Pokémon's heart, and explains the whole conflict was because of Arceus being close to awakening. She also tells them that her ancestor Damos betrayed Arceus and stole the Jewel of Life, sending it into a rage and a slumber. Sheena plans to return the Jewel to Arceus.
