Jax and Xander, now both working for the Earth Confederacy Intelligence Services, attempt to track down the fugitive Tierney and discover she is searching for a destructive weapon that can potentially destroy the entire Universe. Meanwhile, Jax comes face-to-face with a woman she never expected to see again: her mother, Eve.

Jax and the team visit the distant planet where Professor Osborn first discovered Jax as an infant during the Earth-Zatarian War in an attempt to find the Ancients in the hopes of saving our Universe; but is dealt a tragic blow when Ralen suffers a loss that will change him forever.
