A secret military base is being used to research and breed a deadly parasite, thought to have been exterminated by the Taelons, which has reappeared in a mutated form among blood worms in New Kenya. Dr. Sitro (Alon Nashman), the scientist heading the project, discovers that the worms will burrow into the neck of a human, eventually making their way to the brain. The victim is dead within an hour, but in the last few moments is impervious to fear. Sitro shares his findings with Ronald Sandoval (Von Flores) and Zo'or (Anita La Selva), who contemplate how to use the parasites to their advantage.

Liam Kincaid (Robert Leeshock) and Renee Palmer (Jayne Heitmeyer) meet with a holographic messenger sent by Hubble Urick, who shockingly reveals that the Atlantic National Alliance (ANA) has successfully negotiated amnesty for all Resistance members. Zo'or himself has guaranteed the safety of all who come forward on the specified "Day of Sanctuary." Although Liam is doubtful about the Taelons' sincerity, he and Renee convince Resistance member Haley Simmons (Christina Cox) to take the opportunity to come out of hiding. Though skeptical, Haley complies. She is hoping for the chance to be reunited with the sister she abandoned years before in order to pursue the fight against the Taelons.

The Taelons' willingness to give amnesty also provokes the suspicions of Justin Kalen (Derwin Jordan), Director of Pan Global Security for the ANA. Using his knowledge of Sandoval's off-shore bank accounts, Justin coerces Sandoval into investigating the Taelons' real plans for the compliant Resistance members. Sandoval agrees to help but clearly has other intentions.

All hell breaks loose on the "Day of Sanctuary" as Haley and her team travel by portal to a waiting group of Volunteers. Unidentified soldiers suddenly attack, and the troops open fire without regard for their own safety. One of them detonates a bomb killing himself, several Volunteers, Resistance members and civilians. Haley is taken to the hospital in critical condition.

Renee escorts Haley's sister, Kathy (Ksenia Solo), to the hospital, joined by Liam and another bomb-wielding kamikaze soldier who tries to kill Haley. As Liam overpowers him, the soldier goes into convulsions and dies. An autopsy at Dr. Curzon's (Nadia Capone) lab reveals that the man fell victim to a parasite that had made him fearless. Meanwhile, Renee learns that the soldier was a Volunteer who had been assigned to a secret training base in Ohio.

While checking out the base, Liam meets Colonel Bastian (Bill Lake), the man in charge of the Volunteers on the night Haley and the Resistance members were attacked. Bastian, who lost five men in the strike, is also eager to find out who launched the assault. He shows Liam an area of the base that is off-limits and protected by an energy fence. He provides him a blueprint of the base.

Liam and Renee visit Dr. Curzon, who has developed an antidote for the parasite. It must be injected into the victim within 60 seconds of being bitten. She has also learned that each parasite gives off an electromagnetic impulse that helps it find others like itself. With a scanner to help him track these impulses and a syringe containing the antidote, Liam returns to the base that night with Renee as lookout. While Liam searches for the parasites, Sandoval is in another area of the base ordering a group of kamikazes to kill Kalen.

When Liam finds the lab of Dr. Sitro, he sets a fusion grenade, but the doctor suddenly appears and opens fire. As Liam dives for cover, he loses the syringe and is bitten by one of the parasite-infested blood worms. He shoots Dr. Sitro and escapes from the building just in time for Renee to administer the antidote. The grenade explodes behind them, incinerating the lab.

The next day, Kalen picks up Sandoval in his limo. Sandoval tells him that he had to destroy the breeding facility. He exits the car, leaving behind a charred tactical global device that had belonged to one of the kamikazes. Kalen's limo pulls away. A few seconds later, it explodes.

When Liam returns to the hospital to visit Haley, he finds Renee waiting for him. She breaks the tragic news that Haley had an embolism in one of her arteries and died in her sleep.
