The phenomenon of the "pocket monsters" marches on with this animated sci-fi adventure for kids. Famous Pokémon trainer Ash Ketchum (voice of Veronica Taylor) is en route to a special water race for Pokémon in Altomare with his loyal companion, Pikachu, but when they arrive they discover there's bigger game afoot than the race. Annie and Oakley are a pair of female villains determined to steal the all-powerful jewel known as the Soul Dew. However, the jewel is guarded by two especially vigilant Pokémon, Latios and Latias, so the thieves must capture the creatures before they can make off with the enchanted artifact. Annie and Oakley are able to put Latios in captivity, but not before Ash and his friends arrive on the scene. Will Ash and Pikachu be able to free Latios before the thieves can capture the Soul Dew and use its power to control all they survey? Pokémon Heroes is the fifth feature film released in the United States based on the popular Pokemon animé series. ~ Mark Deming, All Movie Guide
