- 2199 AD: the human race will be extinct in one year’s time. Meteor bombardment by the mysterious Gamilas aliens has made the Earth’s surface uninhabitable. Young officers Susumu Kodai and Daisuke Shima retrieve a message offering aid from the enigmatic planet Iscandar. In answer, the revolutionary Space Battleship Yamato is dispatched on a 148,000 light-year journey to reach Iscandar and bring help back to Earth.
The Yamato is commanded by Captain Okita, a taciturn veteran, but many of its crew, including Kodai and Shima, are inexperienced. Together they must defy the space fleets of a tyrannous intergalactic empire. They must also contend with threats from within the Yamato itself, and manage the strange, untested technology which sustains the ship and its powerful Wave Motion Gun. Can they travel to Iscandar and return to save humanity before the year is out?
