Ash and friends are lost while on the trip to Solaceon Town. They find a mansion nearby and decide to check it out. When they approach they are attacked by an young girl named Marble, her Luxray, and a bunch of security guards, who believe they are thieves. The owner comes out and the misunderstanding in resolved. The owner, Matthew, reveals that three criminals want to steal his treasure the Old Charm, at 8:00. Ash, Dawn, and Brock agree to help out. It turns out that Team Rocket are the thieves, and they make off with the treasure. Their plan ends abruptly when their balloon pops and crash lands in another part of the mansion. Everyone heads to get there, but Team Rocket falls prey to the mansion's traps. Now it is up to Ash, Dawn, Brock, and Marble to find Team Rocket and get the Old Charm back, but with a mansion full of traps and a disobedient Luxray, that may be harder then planned.
A young boy named Ash Ketchum embarks on a journey to become a "Pokemon Master" with his first Pokemon, Pikachu. Joining him on his travels are Brock, a girl-obsessed Rock Pokemon Trainer, and Misty, a tomboyish Water Pokemon Trainer who may have a crush on him. Ash and Co. end up traveling through various regions, including Kanto, the Orange Islands, and Johto, and then enter the Pokemon League competitions there.
Along the way, they run into many confrontations with Jessie, James, and Meowth, a trio of Pokemon thieves who are apart of an evil organization called "Team Rocket". But every time Team Rocket try to do their evil deeds, they fail thanks to Ash and his Pokemon.
