Gundam Wing: Endless Waltz is both the prequel and the sequel for the Gundam Wing anime series. It takes 1 year after the big war between earth and the colonies. A few times during the movie, the characters have flashbacks of how they became the gundam pilots.
Relena, now a deputy Foreign Minister for the Earth Sphere United Nation, is hidnapped while on her way to colony L3-X-18999. To her astonishment, the one responsible for her abduction is Mariemaia Khushurenada, head of the Barton Foundation. However, it later becomes clear that Mariemaia is just a puppet controlled by her grandfather, Dekim Barton, to accomplish his second scheme of total control over the Earth sphere. The first scheme had taken place at the beginning of Operation Meteor, when Dekim's son, the real Trowa Barton, was supposed to have gone to Earth, help the other Gundam pilots in their mission and then wipe them out, while his father was taking control of the government. But instead, Trowa was murdered and replaced by a nameless soldier. His first plan having failed, Dekim wants to try again, this time by using the name of Mariemaia's father, Trieze Kushurenada. Heero and Duo, having learned of Relena's disappearance, decide to investigate and send Quatre on a dangerous mission to recover the Gundams before they are destroyed in the sun. At the same time, Trowa learns about Dekim's latest bid for power and decides to stop him. However, as he tries to destroy Dekim, Trowa is stopped by Wufei, now one of Mariemaia's forces....
