Join Ash accompanied by his partner Pikachu, as he travels through many regions, meets new friends and faces new challenges on his quest to become a Pokémon Master.
In order to escape a greedy Pokémon hunter, Celebi must use the last of its energy to travel through time to the present day. Celebi brings along Sammy, a boy who had been trying to protect it. Along with Ash, Pikachu, and the rest of the gang, Sammy and Celebi must encounter an enemy far more advanced than the hunter, with the fate of the forest hanging in the balance.
Ash, Pikachu and the gang try and stop a pair of thieves hiding out in the canals and alleyways of Altomare, the age-old water capital. Joining the adventure are two new legendary Pokémon, a pair of siblings named Latias and Latios, who serve as peacekeepers and protectors of the Soul Dew — a priceless treasure with a mysterious power.
