At One Taelon Avenue, Senior Scientist Dr. George Sato (Robert Haley) begins a test with an ID shuttle prototype. Colonel Bud Ackers (Wayne Ward) is sealed in the cockpit and Sato and Joshua Doors (William de Vry) take their places in the control booth. Sato is informed the temperature in the shuttlecraft is rising and Ackers cries out to abort the test. Sato complacently continues and the craft explodes, sending everyone ducking for cover while Sato calmly watches.

Later, Joshua Doors tries to persuade Renee Palmer (Jayne Heitmeyer) to leave Doors International and join him at One Taelon Avene. Jonathan Doors (David Hemblen) encounters his son in Renee's office and the two exchange opinions about business and the ID Shuttle Program. Joshua restates his offer to Renee and leaves. Jonathan Doors, concerned about his son, asks Liam Kincaid (Robert Leeshock) to find out what's really going on at One Taelon Avenue.

At One Taelon Avenue, Renee meets with Joshua while Liam is tracked by Control, covert artificial intelligence, as he investigates the accident. After Liam questions Beeks about Ackers accident, he enters Sato's office and discovers the Taelon-designed Control System. He peruses reports until Sato enters and shoves him out of his office. Liam forcefully holds Sato but as soon as Sato calms down, he becomes paranoid and begins rambling. Control calms Sato and Liam offers him help, but Sato continues rambling and staggers out of his office. Liam tries to exit Sato's office, but he becomes locked inside. He calls Renee for assistance, but both of their globals cut out. Renee leaves to find Liam, but she becomes trapped in the elevator. Control informs Renee that assistance is on the way and Renee calmly waits. Control then tracks Sato to the test lab and begins a bio-purge function. Sato tries to escape the reconfiguring energy walls but they trap and disintegrate him.

Meanwhile on the mothership, Zo'or (Anita La Selva) and Da'an (Leni Parker) review the micro-camera coverage of Sato's demise. Da'an is concerned that Control may be overriding the Taelon programming and creating its own agenda. Sandoval (Von Flores) reports he has begun an investigation at One Taelon Avenue, but is ordered by Zo'or to close his investigation and allow the local police and the building security to handle matters. Later, Renee and Liam question Joshua about the ID flight project accident reports, but Joshua does not have any answers and does not seem to care to investigate.

Joshua again approaches Renee about joining One Taelon Avenue. When Liam meets with Sato's wife Arlene (Cheryl MacInnis), she suggests her husband was murdered by the project. She tells Liam that as the project progressed, her husband became more obsessed and insane. Later, Jonathan Doors draws parallels between Sato and Joshua's schizophrenic behavior and involvement with One Taelon Avenue. On the mothership, Zo'or initiates contact with Control. Zo'or assures Da'an that Control is suppressing human creativity and any possible threat to Taelon interests, but Da'an is concerned about Control's increasing aggression and independence. Zo'or tries to initiate override measures but Control has mutated beyond Taelon authority.

Meanwhile Control exerts its will over Renee and she accepts a position at One Taelon Avenue. Later, Renee delivers Sato's project discs to Augur's (Richard Chevolleau) lair and assures Liam and Augur there is no evidence of a conspiracy. Jonathan and Joshua Doors discuss business and Joshua expresses his intentions to raid or merge with Doors International and offers Jonathan the position of Chairman Emeritus. Jonathan shakes Joshua while he pleads with him to come to his senses. When Jonathan leaves, Control again exerts its will over Joshua. Augur hacks into One Taelon Avenue's system, but does not find anything unusual. He meets with Zims (Balazs Koos), a comp-system engineer who worked on the building. Zims explains that the Taelons installed The Artificial Intel program with Control Core and escaped after installation through underground routes. When Augur purchases the plan disc from Zims, he discovers Sandoval has also purchased a copy. Meanwhile, Renee, now employed at One Taelon Avenue, persuades Jonathan to meet and discuss a full partnership on the Shuttle Program with Joshua.

Augur's analysis reveals that Control Core is sending electrochemical signals into the One Taelon Avenue building that manipulates free will and also affects Taelon intellect. Augur suspects that Control Core is now acting on its own without Taelon directives. Augur supplies Liam with a neural-adrenaline simulator wristband to block the Control Core's cerebral manipulation. Augur and Liam visit Renee just as she is about to return to One Taelon Avenue. Liam grabs her as Augur clamps on a wristband. Renee quickly returns to herself. She then realizes Jonathan is on his way over to meet with Joshua, which Control Core could perceive as a threat. When Jonathan enters One Taelon Avenue, Control marks him as "Terminate." Zo'or and Da'an discover that Control is operating irrationally and has activated the purification function throughout the entire facility. Sandoval is ordered by Zo'or to evacuate the building and destroy the operational hardware. At One Taelon Avenue, Joshua is on his way to meet his father. Upon Control's command, he pulls out a weapon and is ready to execute Control's orders. Augur informs Renee and Liam of Jonathan and Joshua's locations and tells them that the building has initiated the purification function.

Meanwhile, Sandoval plants Taelon grenades at the heart of the Control Sphere. Control tries to exert its will upon Sandoval, but it doesn't work. Sandoval removes the bio- engineered control core, stores it, and detonates the grenades. Joshua meets his father and draws his gun. Jonathan offers Joshua his simple and honest sentiments hoping to cut through Control's manipulation. Joshua lowers his weapon, but Control realizes it has lost its power and forms an energy wall to kill Joshua. Jonathan pushes his son out of the way, but the energy wall singes Jonathan and sends him over a balcony. Free from Control, Joshua tears down the stairs and holds his father as he dies in his arms.

Da'an and Zo'or watch the elaborate funeral procession of Jonathan Doors from the mothership. Doors' death launches an investigation into One Taelon Avenue and a debate about entering into technological co-ventures with the Taelons. Sandoval enters the bridge and opens the containment case that holds the Control Core, sending both Taelons into catatonic states. Sandoval pockets the Control Core and Da'an and Zo'or come out of their stupors. Sandoval reports on the containment measures at One Taelon Avenue and leaves the Bridge with his new weapon. Renee, Liam and Augur watch the funeral coverage and Renee announces that Joshua will be elected to run Doors International. Augur questions whether Joshua will continue to support the Resistance.
