Fifteen years after the Galaxy Quest sequel series ended, the producers want to reboot the franchise with a hot young cast. After the death of Alexander Dane, and Tommy Webber being confined to a wheelchair, the rest of the cast think that their time is over, and someone else needs to take the reigns. However, at the same time, Mathesar and the rest of the Thermians state that they need their help once again, but after all that has happened, they don't think they can. But, Jason thinks he can relive his glory days one last time, and along with a new cast, they help the Thermians against a new nefarious villain.
