"Gotta catch 'em all!"

Ash finally reaches the Indigo Plateau, home of the Pokémon League conference. Before the tournament begins, they plan on lighting a ceremonial cauldron with the flame of the legendary Pokémon, Moltres. Ash, as a participant, is free to carry the flame but when Team Rocket steals it, the tournament may be cancelled.
