After the Galaxy One is hacked by the Infinity Guard, Gary has to harvest energy from a nearby star to reignite the engines; the radiation poisoning from the star sends Gary into a trance of painful memories; Gary and Quinn are finally reunited.
Gary Goodspeed is a boisterous yet inept astronaut who, in the midst of working off the last few days of his five-year sentence aboard the prison spacecraft Galaxy One, encounters a mysterious planet-destroying alien. Soon, he befriends the alien, whom he names Mooncake, and discovers that Mooncake is wanted by the forces of a powerful telekinetic creature known as the Lord Commander. Together, with the ship's computer H.U.E, an army of similar but unfalteringly loyal robots, and a growing crew of new shipmates, Gary and Mooncake embark on a quest to save the universe, all while trying to uncover the mystery of what "Final Space" really is.
