At the Taelon Embassy, Da'an (Leni Parker) bids farewell to Liam Kincaid (Robert Leeshock), telling him he is about to embark on a "final" journey. The Taelon refuses to reveal his destination despite Liam's protests that, as a Companion protector, he is bound by duty to know of Da'an's whereabouts. Da'an suddenly traps Liam in an energy field and makes his getaway. When Liam meets with Zo'or (Anita La Selva) and Ronald Sandoval (Von Flores) to figure out a way to find Da'an, Zo'or insists that he receive a viral neural implant so that Sandoval can monitor him while he searches for Da'an.

At Doors International, Liam alerts Renee Palmer (Jayne Heitmeyer) that he now has a neural implant that allows Sandoval to see and hear everything he encounters. The danger of the implant is clear to Renee, particularly with regard to Liam's Resistance activities. She enlists the help of J Street (Melinda Deines) to try to find a way to get rid of the implant without being seen by Sandoval.

Da'an arrives at the derelict Freedom space station and is met by rogue Russian chairman Mikael Federov (Garwin Sanford). Da'an has brought a cold-fusion energy core with him that he installs in the station's power grid, bringing the station to life, along with a portal that transports a Jaridian named Balvak (Kent Staines) to the Freedom. Meanwhile, Street and Renee ambush Liam in an alley and use a gas grenade to knock him unconscious while staying out of sight of Liam and Sandoval, via the implant. They carry Liam to Augur's Lair, where Street utilizes a quantum teleporter to create a temporary "quantum twin" of Liam.

Zo'or informs Sandoval that he has found the space station Freedom hiding amid the rings of Saturn. He believes Da'an is onboard. Having learned of recent communications between the Jaridians and Da'an, he suspects the Taelon of setting up a transportation portal for the Jaridians, effectively providing them with a gateway for invasion. He orders Sandoval to the space station, instructing him to kill the traitorous Da'an.

The real Liam regains consciousness in the alley and is treated by a medical team until Sandoval intervenes, having learned of the location via Liam's implant. The "quantum" Liam, however, watches from across the street with Renee, his implant unreadable to Sandoval because of a slight variance in frequency. With Da'an now a fugitive, the real Liam is relieved of his Companion protector duties by Sandoval and taken into custody.

Da'an and Balvak (Kent Staines) prepare to begin what Da'an terms the "final moment," a joining of the two species to resurrect the original form from which they were both derived. An undercover Resistance worker contacts Renee and the "quantum" Liam, telling them of Da'an's whereabouts. They transfer via portal to the Freedom, only to be incepted by Federov, who holds them at gunpoint. The three walk to another section of the station, where they watch Da'an and Balvak come together in a bright glare. The two forms merge, creating a third form that flickers in and out. The "quantum" Liam recognizes it as an Atavus, a life form like those that existed eight million years earlier, before the Taelons and Jaridians embarked on different evolutionary paths.

There is a sudden explosion and Federov rushes to an exterior view port where he sees a Taelon battle cruiser approaching. It's Sandoval! Amidst the commotion, the Atavus hurls two bolts of Shaqarava energy, blowing out the view port before exploding in a shower of sparks. While Da'an is unharmed, Balvak is killed. As Da'an, Federov and Renee rush to a shuttle to escape the station, the "quantum" Liam stays behind to fend off Sandoval's storm troopers. The shuttle clears the station just as Liam triggers the cold fusion core and blows up the whole station, including himself.

Upon returning to the Taelon Mothership, Da'an removes the neural implant from the real Liam. With the cinders of a dead Jaridian in his possession, the recently condemned Da'an is now a hero to the Taelons.
