Following her first encounter with the Atavus, Renee Palmer (Jayne Heitmeyer) awakens in a military hospital. She is detained by Hubble Urick (Frank Moore), who refuses to believe her story about the new alien threat. J Street (Melinda Deines), evading the FBI agents who took Renee into custody, dons a disguise and rescues her friend from the hospital.

Onboard the Mothership, Sandoval approaches Howlyn (Alan Van Sprang) and the female Atavus, Juda (Guylaine St. Onge), proposing that they spare him so he can help them fulfill their goal to consume the 5.1 billion humans that reside on Earth. When they question his motives, Sandoval assures them that the demise of humanity would be payback for him, given that his efforts to keep Earth safe from the Taelons were met with rejection and betrayal from his own kind. He also remains bitter over the nuclear strike on the Mothership that has left him disfigured.

Realizing she needs Urick's help to combat the Atavus, Renee arranges to meet him secretly. Hoping to convince him that her story about the Atavus is true, she brings a video recording of the aliens that was shot by Street. Renee meets Urick in a dark alley, but is barely able to give him the recording before suddenly being ambushed by a SWAT team, apparently double-crossed by Urick. She is able to escape, however, and returns to Street's trailer home.

Meanwhile, Sandoval discovers the Taelon Raj'el (Helen Taylor) in the Atavan chamber on the Mothership. He rejects Raj'el's pleas for help in destroying the Atavus, and instead locks Raj'el in the chamber.

While Urick is unable to confirm the authenticity of Street's Atavus video, he begins to suspect that Renee has been telling him the truth and sends an aid to find her. Back onboard the Mothership, Howlyn decides to decline Sandoval's offer to help and attacks him, but is fended off by a mysterious force emanating from Sandoval.

Soon after, Renee and Street receive a video communication from Sandoval begging for their help. He tells them that he had to seal himself in the ship's bridge to escape the deadly Atavus and offers to lower the vessel's security shields, which would allow Renee to gain access to the ship via shuttlecraft. Renee immediately takes off in a shuttle, planning to rescue Sandoval and set a charge that will blast the ship and the Atavus into oblivion.

When Renee arrives at the Mothership, she discovers Sandoval has betrayed her. She is taken prisoner by Howlyn. Meanwhile, Juda seduces Sandoval and uses her mysterious healing abilities to cure him of his radiation burns and reverse his disfigurement. In another part of the ship, Raj'el escapes from the chamber and sets off to free Renee, who encounters Howlyn once again. He tells Renee he is unable to consume her, however, because of the same mysterious force that protects Sandoval. Nevertheless, he attacks her but Renee uses a slender sword she had concealed to fend him off. Cutting off one of his hands in the process, Howlyn hollers in agony and Renee flees the ship via the shuttle.

Renee visits Urick at his office in Washington and, depositing Howlyn's severed hand on his desk, finally provides irrefutable proof of the existence of the Atavus.
