Having already provided proof of the Atavus threat in the form of Howlyn's severed hand, Renee Palmer (Jayne Heitmeyer) is asked by Hubble Urick (Frank Moore) to present her case before a meeting with the FBI. Again displaying Howlyn's hand as evidence, she pleads with FBI Deputy Director Ryan Patrichio (Noam Jenkins), chairing the meeting in Urick's absence, to dispatch an elite task force to the Taelon Mothership to destroy the Atavus. Instead, Patrichio assigns Interpol's senior strategist, John Besson (James Downing), to investigate Renee's claims. Furious, Renee storms out and takes off for the Mothership alone.

Onboard the Mothership, Sandoval (Von Flores) informs Howlyn (Alan Van Sprang) and Juda (Guylaine St. Onge) that the Taelon ship is fully functional except for the weapons supply. Infuriated he can't destroy humanity with the press of a button, Howlyn is eventually convinced by Sandoval and Juda that the Human race is more useful to the Atavus alive. The three devise a "joining" procedure in which they can create hybrids from Humans, essentially enslaving them. Sandoval suggests they start with small groups of people, especially the advisors to world leaders. After their "joining," these people could be returned to their jobs with a newfound loyalty to the Atavus. Howlyn accepts the idea, but insists that Renee be among those abducted for "joining."

Meanwhile, Renee sneaks aboard the Mothership where she finds Raj'el (Helen Taylor) locked up in containment cell. Raj'el reveals that his energy is toxic to the Atavus, giving them no choice but to keep him in isolation. When he tells Renee that he senses that other Humans are now onboard, she goes to investigate and watches as several Humans are led into sarcophagus-like pods in which they are "joined" with Atavus. Sandoval sees Renee and sends a security team after her. She manages to escape the ship, but not before planting a modulating device that will temporarily lower the ship's security shields within the hour.

Returning to Earth, Renee contacts Urick and tells him that the "joining" is underway, and they only have an hour to infiltrate the ship, but he refuses to comply. J Street (Melinda Deines) alerts Renee that she has detected portal activity in Washington, where the new hybrids are returning to Earth following their "joining" with the Atavus, The two race to the site.

Urick has a change of heart, and orders Besson to lead an assault on the Mothership. Besson tricks Urick into entering a portal with him and takes him directly to the Mothership and into the hands of Howlyn. Howlyn shows Urick his regenerated hand before stabbing him in the chest.

Renee and Street arrive at the Washington portal where they encounter Besson as he returns from the Mothership. Renee notices an Atavan gleam in his eye and realizes Besson is now a hybrid. He quickly takes her by portal back to the ship, but Renee is able to escape her captor just as the device she had planted activates. With Urick slipping into shock from his chest wound, Renee is able to portal him back to Street for medical attention while she stays behind to look for a way to permanently disarm the ship's shields.

As Renee tries to access the main shield controls, Sandoval captures her and takes her to Howlyn who forces her into a pod to "join" with him. Like Raj'el, however, Renee's Taelon energy, which she had acquired in a previous encounter with Da'an, repels him. Howlyn and Renee exit the pod and a fight ensues, but they are interrupted by Raj'el, who distracts Howlyn long enough for Renee to escape.

Renee returns to Earth and visits Urick in the hospital. She then contacts Patrichio so that Urick can order an immediate strike on the Mothership while its shields are still down. Before Urick can give the command, however, he slips into a coma.
