"The stage is set in "Alto Mare", the most beautiful town in the world.
Many Pokemon are in the waterway and air garden that stretches and surrounds the town.
The island coexists with man. Ash and other people encounter Ratiasu and Ratiosu in the town.
Ratiosu (the blue one) is an elder brother, Ratiasu (the red one) is Ratiosu's younger sister, and "the teardrop of the heart" is hidden and protected in town by them. And there is a sister of globally famous [can't make out word] which aims at the "drop of the heart."
Ash and others are involved in the incident that Zanna caused (Zanna is a Jewel thief so I she probably stole the tear). The town becomes involved in a massive flood from having broken the seal of "the teardrop of the heart", and "Alto Mare."
Will Ash and co be able to handle this crisis this time?"

These pokémon are featured in the coming game boy advance pokémon game.

Like all other movies this comes with a Pikachu Short at the start
