It is the 11th animated film in the Pokémon film series created by Satoshi Tajiri, Junichi Masuda and Ken Sugimori, and serves as a direct sequel to Pokémon: The Rise of Darkrai (2007). In the film, a researcher called Zero seeks to sacrifice and absorb the interdimensional abilities of a Pokémon known as Giratina, which has surfaced in Zero's world following the events of the previous film, so that Zero can become the ruler of Giratina's world. Meanwhile, the Pokémon trainers Ash Ketchum, Dawn, and Brock escort a flower-bearing Pokémon called Shaymin, which is being followed by Giratina, to reunite it with other Shaymin at a flower garden. It was released in Japan on July 19, 2008. A sequel, Pokémon: Arceus and the Jewel of Life, was released in 2009. The theme song for the film is "One" by Crystal Kay. Plot Five years ago, Newton Graceland, a researcher of a world exactly opposite to the world of reality called the Reverse World, built a device to absorb the abilities of the Pokémon Giratina, the ruler of the Reverse World, to travel freely between the two worlds. He canceled the project upon learning that the process would kill Giratina. The blueprints were deleted but Newton's assistant Zero never forgot them. Later, time and space, two dimensions that should never have been in contact, collided and unraveled. Dialga, the Pokémon which rules over time, and Palkia, which controls space, then fought each other in Alamos Town, both believing the other to have violated their territory. The distortions in time and space have defiled the Reverse World with pollution, angering Giratina. Giratina captures Dialga and drags it into the Reverse World. Shaymin, a hedgehog-like Pokémon which bears flowers, gets caught on Dialga’s back when the portal opens. A frightened Shaymin uses its powers to escape through a portal back to the world of reality. Dialga follows Shaymin after it disables Giratina's ability to venture to the world of reality by trapping it in an infinite time loop. Shaymin runs into the Pokémon trainers Ash Ketchum, Dawn, and Brock, who agree to take Shaymin to the Flower Garden in the mountains, so it and others of its kind can migrate and grow a new garden,
