Captain Lili Marquette (Lisa Howard) and Agent Ron Sandoval (Von Flores) were on duty aboard the Taelon mothership when they were alerted to two unidentified shuttles which suddenly appeared in Earth's airspace. One shuttle was clearly chasing the other, but before contact could be made, the pursuing shuttle crashed into a mountain and the target shuttle disappeared from the air traffic control screen. Unobserved by the mothership, the Taelon pilot managed to land his craft and emerged from the shuttle in his natural "blue" form.

Meanwhile, Major Liam Kincaid (Robert Leeshock) informed Augur (Richard Chevolleau) that Da'an (Leni Parker) had left the Taelon mothership without telling him where he was going. Suddenly, Lili called them at Augur's to ask for help in tracking the renegade shuttle, which was not from the Taelons' Earth fleet. On board the mothership Zo'or (Anita La Selva) was cryptic about the missing pilot, commanding Sandoval and Lili to apprehend him dead or alive. Lili and Sandoval realized the fugitive was an obvious threat, if Zo'or was willing to kill another Taelon.

During this time, Da'an was on a spiritual retreat in a virtual Taelon homeworld, immersed in a primitive sacred ritual. Back on Earth, the fugitive Taelon revealed himself to two boys whom he encountered playing in the woods. The kids were frightened at first, until the Taelon touched one of them and was able to cloak himself with a human exterior. He told the boys his name was Bel'lie (Fiona Highet) and that he needed a place to hide. They took him to their clubhouse and swore to keep his location a secret. After communicating with Lili on the mothership, the Resistance knew they only had a thin margin to find the Taelon before Zo'or did, and they sent out extra troops to the shuttle crash site. When the Resistance fighters flushed the boys out of the bushes near their secret hideout, Liam worked quickly to win their trust to take him to Bel'lie.

Zo'or had also been maneuvering to get to the bottom of the Taelon defection, and went to Da'an's place of retreat to tell him about the shuttle crash. When Zo'or told Da'an the fugitive was Bel'lie, Da'an was deeply unsettled. Liam discovered why, when he confronted Bel'lie in the clubhouse and the defector told him he had come to help humans fight their Taelon oppressors. In the midst of their dialogue, shuttles from the mothership attacked the area, forcing the Resistance to flee with Bel'lie. Liam had to decide whether to turn Bel'lie over to the Taelon forces, but decided to shelter him at Augur's instead.

Liam proceeded to the mothership, where he demanded that Zo'or tell him where he could find Da'an. Zo'or refused to let Liam interrupt Da'an's sacred pilgrimage, and re-issues his order that they find the defector at once. Liam returned to Augur, where he grilled Bel'lie about his mission. Bel'lie told the Resistance members that the Taelons were subjugating hundreds of planets in their war with the Jaridians. He told them he had come to Earth to take back human fighters to join forces with other renegade Taelons, and that his shuttle databanks contained proof of a Taelon underground. To further prove his integrity, Bel'lie agreed to sever his link with the Taelon Commonality despite the risk that he would regress into an Atavus, a primitive alien life form, which Taelon and humans alike would seek to destroy.

In the mothership shuttle bay, Lili barely had time to download Bel'lie's databanks from the recovered shuttle before Sandoval ordered the airship torn apart. She transmitted the information to Augur's, where Bel'lie talked to Liam about his crusade. When Liam tried to persuade Bel'lie to confide in Da'an, the Taelon shocked him by announcing Da'an was the architect of the Taelon strategy of galactic destruction, and that Da'an himself had banished Bel'lie to the farthest reaches of the galaxy for opposing his will. Confused by Da'an's disappearance on his supposed retreat, Liam didn't know what to believe.

As Liam and Lili tried to find where Da'an had gone, the operation the Resistance had used to separate Bel'lie from the Commonality suddenly went wrong. Before anyone could stop it, Bel'lie regressed into an Atavus, and defended himself with shaqarava blasts as he escaped from Augur's hideout. Liam suspected Bel'lie may have aided his transformation so he could find Da'an and kill him, no longer prevented from doing so by his Taelon consciousness . He followed the Atavus to Da'an's office, then through the portal which led to Da'an's virtual retreat. Liam arrived on Da'an's virtual mountain top just as Bel'lie the Atavus attacked Da'an. Liam stepped in to defend the Taelon leader and, after grappling with the Atavus, sent him hurtling off a cliff. Liam turned to Da'an to confront him with Bel'lie's accusations, but Da'an could only say he was no longer the Taelon he once was. With the proof of Bel'lie's databanks, Liam and the Resistance were left wondering if Da'an was truly sympathetic to their cause, or was just using it as a ruse, or whether Zo'or had set up Da'an to be killed by Bel'lie in his own deadly game.
