The History of Trunks tells the story of Future Trunks and his life during the time where the androids have the world under siege. It is unique among Dragon Ball movies/specials since it is actually based from a brief chapter in the Dragon Ball manga, called "Trunks The History - The Lone Warrior". The special changes several key plot points for drama (such as that in the manga Trunks was capable of transforming into a Super Saiyan before Future Gohan's death).
