Ash and his friends are on their journey through the Orange Islands—but even this seemingly quiet chain of islands dotted throughout the waters far south of Kanto has its own mysteries, adventures, and Legendary Pokémon! Lawrence III certainly knows it, which is why he's now traveling to the different islands and capturing the three Legendary birds—Moltres, Articuno, and Zapdos. But even with all their power, those three are merely a stepping stone to an even greater prize: Lugia, the guardian of the sea!
Of course, Ash is completely unaware of all this when he arrives at his latest destination. The islanders have big plans for him, too, but nothing so sinister—they want him to take part in a ceremony to gather three elemental balls from different islands. When the weather across the world goes out of control, this task takes on a new importance, as the capture of the Legendary birds has thrown the environment out of balance. With Lugia's help, can Ash be the “chosen one” that everyone turns to?
