On the Mothership, Da'an (Leni Parker) enters a secret research deck where Dr. Andrea Mazar (Sara La Fleur) is deciphering Ma'el's logs. Dr. Mazar pulls out a pulse pistol and fires at Da'an, leaving him flickering between flesh and energy. Dr. Mazar stands over Da'an and a barrage of painful memories of a car accident flood her mind. She grabs her laptop computer, Ma'el's logs and heads to the portal station. Volunteer Joan Price (Lexa Doig) hands Dr. Mazar a backpack and she escapes through the portal as alarms sound.

Meanwhile, Sandoval (Von Flores) convinces Mit'gai (Anaya Farrell) to harbor Da'an in the medical lab. Liam Kincaid (Robert Leeshock) arrives on the mothership and Sandoval refuses to let him visit Da'an. Sandoval assigns Liam to find Dr. Mazar and terminate her on sight for the attempted murder of Da'an. Later, Liam and Renee Palmer (Jayne Heitmeyer) learn that Dr. Mazar is a chaos theoretician specializing in quantum mathematics, who boarded the mothership over three years ago and never left. Upon questioning Volunteer Joan Price, Liam discovers that Dr. Mazar was an orphan and her husband had been killed during a Resistance action.

Later, Zo'or (Anita La Selva) questions Mit'gai about the rigid restrictions placed on Da'an's visitors because he wants to interrogate Da'an about Dr. Mazar. Meanwhile, a recovered Da'an becomes concerned about locating Dr. Mazar and keeping the knowledge of Ma'el's logs from Zo'or. At Augur's (Richard Chevolleau) lair, Holo-Girl (Topaz Hasfal) reports to Augur, Renee and Liam that Dr. Mazar's real identity is Emma King, the wife of successful businessman Philip King. Emma King was kidnapped and supposedly killed in a hostage situation for which Sandoval conducted the negotiations. Renee decides that Dr. Mazar may have Taelon implanted memories and she approaches Philip King (Stewart Bick) as a Doors executive with a business proposition to determine if he's working with the Taelons. After her meeting, Renee reports to Liam and Augur that King is not a Taelon collaborator. Volunteer Joan Price alerts Liam that Portal Authority has traced Dr. Mazar to the Glad Stone Hotel in Chicago. Liam arrives at the hotel minutes before Sandoval and convinces Dr. Mazar to flee as he downloads her files to Augur. Liam escapes just as Sandoval orders the Volunteer Officer to blast the room. The Volunteer reports a missed hit and Sandoval orders the city to be sealed off.

Liam returns to Augur's lair and they determine that Dr. Mazar was interpreting a blend of Taelon symbols and Sumerian Hieroglyphs. Liam and Augur realize she cannot continue her work without a specific computer and they search for her computer source to track her down. Later on the mothership, Zo'or bursts into the infirmary and discovers a fully recovered Da'an. Zo'or questions Da'an about Dr. Mazar's attack, but Da'an claims to have no information. After Zo'or leaves, Da'an calls Sandoval and expresses the pressing urgency of locating Dr. Mazar. Meanwhile in an abandoned factory, Dr. Mazar receives delivery of a computer and begins to work.

Later, Augur informs Liam of the computer delivery and portals Liam into Dr. Mazar's room just as Sandoval and Volunteers burst through the door. Liam returns fire, detonates a smoke grenade, and he and Dr. Mazar escape through the portal. Later at Renee's office, Liam and Renee divulge to Dr. Mazar their Resistance ties and reveal to her that her true identity is Emma King. They also tell her that she has been implanted with fake memories. Emma admits to a compelling need to find someone on Earth and Renee tells her that she is looking for her husband Philip.

Meanwhile, Zo'or interrogates Volunteer Joan Price, while Emma completes the holographic image in Renee's office. Emma explains that in order to read Ma'el's extensive research document, it requires the touch of both a human and a Taelon. Renee refuses to share the information with the Taelons but Emma informs them after removal from the protective environment of the mothership, the relic is degrading and must be read immediately.

Later, Zo'or informs Liam of the enlightening conversation he had with Volunteer Price. Liam confirms finding Emma, terminating her and recovering the relic. He agrees to meet with Zo'or at the Taelon Embassy. Together, Liam and Zo'or open the document, a primer on the genetic manipulation of the human species. They discover humanity to be the missing evolutionary link between the Taelons and the Jaridians, and that without humanity both species will perish. Zo'or tells Liam that they will work together to discover the remaining pieces of information from the document.

Zo'or confronts Da'an about his exclusion from the research on Ma'el's document, ensuring such an omission will never occur again. Zo'or then approaches Sandoval about his betrayal, but Sandoval saves himself from execution by stating that he is compelled to serve all Companions. Meanwhile, Liam and Augur discuss the possibility of Augur replicating Zo'or's energy signature to open Ma'el's document and Philip King is reunited with his wife, Emma.
