Team Rocket schnappen sich eine goldene Maske und einen Stab, mit denen sie alle Pokémon beherrschen können…
As our heroes and their Pokémon enjoy another fine meal prepared by Brock, Golbat begins to act strangely and flies away. Brock, Ash and Misty chase after the Flying-type and end up at an archaeological dig. When they meet the intelligent and beautiful archeologist, Tierra she explains her ultra-sonic equipment had just been destroyed and perhaps its errant waves attracted Golbat. She also tells our heroes of an ancient golden mask and scepter, once belonging to a queen who had the power to control all Pokémon. She is now looking for a buried temple said to contain these two priceless artifacts and asks Brock if his Golbat will use it's Sonic attack to help her locate the exact placement of the temple. Overhearing our heroes, Team Rocket employs their latest mechanical menace, the Dig-a-Tron to beat the gang to the temple. When Jessie dons the mask and scepter she has the power to control all Pokémon, even Pikachu! What will become of the Pokémon under Jesse's rule?
Lors d'une de leurs aventures, nos amis tombent sur Tierra, une archéologue. Elle fait des fouilles pour tenter de retrouver le masque et le bâton de la reine des Pokémon ! Mais la Team Rocket est plus rapide et s'en empare avant. Jessie est alors la reine des Pokémon, mais son pouvoir s'étend sur un terrain... limité.
Siguiendo a Golbat, los chicos conocen a Tiera, una arqueóloga que está buscando el cetro y la máscara de una antigua reina que podía controlar a los pokémon salvajes.
Mentre i nostri eroi e i loro Pokémon si godono un altro pasto preparato da Brock, Golbat inizia a comportarsi in modo strano e vola via. Brock, Ash e Misty inseguono il Pokémon di tipo Volante e finiscono per imbattersi in uno scavo archeologico.
Ao ouvir sobre antigas relíquias que permitem ao usuário controlar qualquer Pokémon, Jessie, James e Meowth se preparam para escavar em busca do tesouro de toda uma vida!
