In the year After Colony 195, after decades of oppression from the United Earth Sphere Alliance and its secret weapons organization, OZ, a group of rebels in the space colonies send down five mobile suits known as "Gundams" to overthrow the militaristic regime. Four of the Gundams successfully make it to Earth, but the fifth (Wing Gundam) is intercepted during its descent by OZ's Lieutenant Zechs Merquise and it crashes into the Pacific Ocean. The Gundam's pilot, who goes by the name Heero Yuy, later washes up on shore and is discovered by Relena Darlian, the daughter of the Alliance's vice foreign minister.
