En route to a tournament, 10-year-old Pokémon trainer, Ash, with his friends Misty and Brock, detour to a remote village to see the unique Pokémon that thrive in the forest. While there, they encounter Sam, a young boy who was transported to the future from forty years in the past by a Pokémon named Celebi. Celebi, also called the Voice of the Forest, was wounded by a nasty Pokémon trapper and fled to the future to avoid being captured. Unfortunately, the Pokémon trapper of the future--the Iron-Masked Marauder--is bigger, badder, and meaner. He is pursuing the rare Celebi and not only has the ability to make any Pokémon he catches the epitome of evil, but also has every intention of using his evil device to take over the world. Sam and Ash, accompanied by Celebi and Ash's faithful Pokémon, Pikachu, find themselves in a fight for their lives as well as the livelihood of the forest. Along the way, they encounter the legendary Suicine, reminiscent of a unicorn or Pegasus. Ultimately, the story is a testament to friendship and loyalty, with a surprise plot twist at the end that should be appreciated by fans.
