Ash, Misty and Brock meet Sam, a boy pulled forty years out of his own time when he shielded Celebi from a poacher and the injured Time Travel Pokémon tore open a rift. Celebi recovers at the Lake of Life near the village of Arborville, but the Iron-Masked Marauder, a Team Rocket hunter armed with Dark Balls that bend any Pokémon to his will, is close behind it. Ash, Sam and their friends have to reach Celebi first. This manga adapts the fourth Pokémon film.
