The Passage

Federal Agent Brad Wolgast is assigned to retrieve Amy Bellafonte, a ten-year-old girl selected for a controversial experiment, as a flu epidemic looms over the United States. His mission becomes complicated after forming a connection with Amy, causing him to question his allegiance to the secretive Project NOAH.

Amy and Brad, with Brad injured, flee from Richards in hopes of finding shelter with Brad's former military mentor, while Lila supports them from a distance. At Project NOAH, Dr. Lear contemplates his involvement of Fanning in the research, and as the virus spreads in China, testing on Anthony Carter begins amid growing urgency to find a cure.

Brad negotiates with Sykes and Richards to remain at Project NOAH to support Amy as she undergoes virus testing. After discovering the grim conditions in 4B, he joins forces with others to investigate further. Babcock also reveals details about her personal history.

Wolgast arranges for Amy to leave the facility for exercise, persuading Sykes and Lear to grant permission. As Carter's past is revealed through flashbacks, Fanning's influence over the prisoners in Project Noah intensifies. At the same time, the virals gain control over the staff, prompting Richards and Wolgast to team up against a rogue soldier.

The arrival of high-ranking official Horace Guilder at Project NOAH prompts Brad and Amy to devise an escape plan with unexpected help, while tensions rise between Sykes and Richards as they scrutinize each other's intentions, and hidden history among Lear, Elizabeth, and Fanning comes to light.

As a virus spreads beyond Project NOAH, Guilder and Richards organize a search mission, while Amy's unconventional offer to assist creates tension with Brad. Lear attempts to explain his difficult choices to an alert Elizabeth, and an unexpected link between Sykes and Babcock comes to light.

Brad and Lila reflect on their past as they work together to rescue Amy. Horace Guilder is granted full control of Project NOAH by the Secretary of Defense, alarming Sykes and Richards. Meanwhile, Amy and Carter grow closer as she becomes more involved in Fanning's scheme, and Lear races to assist Elizabeth before time runs out.

Amy's worsening condition forces the group to act quickly as Brad unites them, while Lila and Sykes work urgently to develop a cure. Meanwhile, Richards struggles to maintain control of Project NOAH as Guilder's unexpected staff reductions and Babcock's persistent interference complicate matters.

Amy must make a difficult decision to stop Fanning and the virals from escaping Project NOAH, weighing the risks of a dangerous explosion that could endanger Brad, Sykes, and the virus cure. In the aftermath, unexpected alliances emerge and a significant figure returns to rally the group and restore their determination to survive.
