No real clue what the story will be about. The original series' third film (a TV movie) had the same title as was based on Dessler's return home to Gamilas and Yamato training a new crew for the ship after the immense loss of life during the war with Gatlantis. However that would only be directly after the end of Yamato 2202...this new series is set years later...so where they go from here is anyone's guess.
