Set in the year 2052, Earth has managed to find peace until the arrival of the Death Force - ruthless aliens from a dying solar system - who are desperately searching for a new home. Attacking the Earth with a massive satellite ship called Terror Star, the aliens proceed to terraform the planet to make it their own. For mankind there is one hope: it's up to Colin Collins and a small band of his fellow surviving students to crew a top-secret submersible vessel that can fight the invaders at sea or in space.
 
Note: Episode 1 is ~96 min minutes as opposed to the standard 24 minute long episode. It was later split into 4 episodes on streaming, home media releases and most western dubs.

It is the year 2201. The Yamato has returned from the devastating battle with Emperor Zordar and the Comet Empire. Sanada, Aihara, and Shima are released from the hospital, and go to pay their respects to the fallen crew members at Okita's memorial. They meet Tokugawa's son Tasuke, who says that he will be joining the crew once he graduates from cadet school. The next day at his graduation, he ends up capsizing a boat full of new cadets because they are all too busy staring at the Yamato to watch where they are going. 
After some problems during launch due to the new engine crew hitting the wrong switches and stalling the ship, the Yamato departs on what should be a simple training mission.
