Ash, Misty, Brock and Pikachu come across an abandoned temple that is said to have been the birthplace of the world's most ancient Pokémon guardian, Mew. Shortly afterwards, they are invited to a "Trainer Luncheon Party" on an island off the coast of Vermillion City, but all is not as it seems. Team Rocket also seem to be invested in this, and the two groups rush to get to the bottom of the mysterious invitation, which seems to be connected to the city's missing Pokémon nurse.
