In the year 2199, alien beings attack the last of Earth’s space fleet who are protecting a secret mission. Ace pilot Susumu Kodai retrieves an item on Mars that could save the human race, but learns tragic news about his brother.

Stopping on Saturn’s moon, Susumu investigates a distress call. But a crashed ship isn’t the only thing he finds.

With Gamilan forces hot on their trail, the Yamato must navigate around the burning solar flares of a star.

Having found shelter in a cluster of asteroids, the crew makes an important discovery about the Gamilas’ tactics.

Kodai and Yuki return to a seemingly empty Yamato. Attempts to locate the crew are hindered by a foe who can control memories.

Unbeknownst to General Domel, plots are unfolding on his homeworld. Meanwhile, he plans an ambush of epic proportions against the Yamato.

The Gamilans set their ambush into motion. The two commanders, Domel and Okita, vie for ultimate victory and survival.

With a Wave Motion Gun in Gamilan possession, the Yamato’s only option is to take the fight to Gamilas’ capital. Meanwhile, Kodai is given permission to rescue Yuki.
