A powerful Jaridian (Andrew Jackson) being held for research aboard the Taelon mother ship escaped from the cryogenics lab when a power surge interfered with his containment tank. The Jaridian killed a lab technician and took Captain Lili Marquette (Lisa Howard) hostage inside her shuttle, forcing her to fly off the mothership. Agent Ron Sandoval (Von Flores) sent Major Liam Kincaid (Robert Leeshock) in pursuit and Zo'or (Anita La Selva) ordered Liam to shoot down Lili's shuttle.

After disappearing into interdimensional space, both Lili and Liam's shuttles were drawn into a tractor beam that pulled them off course and inside a huge alien vessel. The Jaridian commanded Lili to follow him into the craft. They were stunned to see that the landing bay was filled with crewless alien vessels, some of which were corroded from eons of neglect. Liam's shuttle also landed in the docking bay. When he exited into the mysterious space ship, he found the walls covered with writing and art, which he could interpret.

As Lili and the Jaridian proceeded into the space vessel, they encountered a water-filled chamber where they were attacked by serpent-like creatures. Liam also stumbled into a water trap and when he fought off one of the serpents, he found it was a mechanical device. Struggling out of the water chamber, Liam was seen by the Jaridian who tried to kill him with a shaqarava blast. As they fought in vicious hand to hand combat, the Jaridian noticed Liam's shaqarava. Liam told the Jaridian that he was part Kimera and that the strange vessel belonged to the extinct alien race. Liam showed Lili and the Jaridian the writing on the wall and explained that the ship was a repository for the accumulated knowledge of the Kimera race. In order to gain the Kimera knowledge, they must prove themselves worthy by running a gauntlet to the core of the ship. Both Liam and the Jaridian knew that the peaceful Kimera would not have designed such a lethal space craft and agreed that the vessel's programming must have been corrupted.

On the Taelon mothership, Da'an (Leni Parker) confronted Zo'or about the Jaridian's escape. Da'an demanded Zo'or's resignation as head of the Synod, since not only was it possible the Jaridian would bring interdimensional flight technology back to his home planet, but his contact with humans would allow him to tell the Jaridian's version of the conflict between the two alien species. Zo'or sent Sandoval out to find the fugitives and kill them all if necessary.

Lili and the Jaridian must make their way through a gauntlet of lethal laser beams. Using his superior eyesight, the Jaridian negotiates the course, only to find a dead end. As the walls start moving together to crush the trio and force them into the laser beams, they worked together to climb over the walls to safety. When they paused to staunch the Jaridian's wounds, he revealed that the Jaridians and the Taelons used to be one race, until the Taelons separated, giving up the shaqarava and the dark side of its power in their quest for spiritual perfection. But the psychic "Commonality" they created destroyed their ability to reproduce. Now the Taelons hope to force a union with the Jaridians by using humans as foot soldiers against them in the total war.

Astounded by the Jaridian's revelation, Lili and Liam continued to make their way deeper into the ship. Liam dropped down a black well that led to a doorway. When he pulled the door open the doorway exploded, smashing him into the ground. When Lili and the Jaridian reached Liam, he showed no vital signs. Lili frantically tried to revive him, but it took the Jaridian's shaqarava to bring Liam back to life. They entered the inner chamber where they found a hologram of a Kimera woman. She informed them she could not reveal the ship's secrets, which enraged the Jaridian. When he threatened her, she struck him down with a blast of power. When it seemed she would next turn on Liam and Lili, Liam reasoned with the hologram and convinced her that the ship's programming must be corrupted since the Kimera never hurt other species. The hologram image followed the only recourse it could and began a self-destruct sequence to destroy the ship.

Liam and Lili collected the injured Jaridian and raced back through the Kimera ship to their shuttles. Liam put the Jaridian on board one shuttle and sabotaged the interdimensional drive unit, giving the Jaridian enough power to fly home before the unit incinerated, destroying its secrets. The Jaridian was grateful to Liam for saving his life, but vowed to return to Earth to confront the Taelons. Lili and Liam boarded their shuttle and returned to Earth, where Da'an's attempt to oust Zo'or had failed, ensuring the Jaridians, Taelons and humans would meet again.
