The Passage

In an attempt to protect Amy, Wolgast convinces Sykes and Lear to let them outside of the facility for exercise. As emotional flashbacks reveal Carter's life leading up to his death-row sentencing, Fanning's hold on those kept inside Project Noah grows stronger. Meanwhile, the virals gain power over the facility's staff, leading Richards and Wolgast to reunite so they can take down a rogue soldier.

With the sudden arrival of a high ranking official, Horace Guilder, to Project NOAH, Brad and Amy begin to strategize a possible escape plan with the help of an unlikely accomplice. Meanwhile, Sykes and Richards begin to question each other's motives, and a shaky past between Lear, Elizabeth and Fanning is revealed.

Tensions are high with a viral on the loose outside Project NOAH, as Guilder and Richards hurry to mobilize a search party. Amy volunteers to help in an unexpected way, causing friction between her and Brad. Lear tries to help a lucid Elizabeth understand the tough decisions he's made while at NOAH. A surprising connection between Sykes and Babcock is revealed.

Brad and Lila flash back through their history together as they plan to save Amy. The Secretary of Defense gives Horace Guilder full authority over Project NOAH, leaving Sykes and Richards terrified for what his plan of attack might entail. Meanwhile, the bond between Amy and Carter is stronger than ever, as he prepares her for Fanning's grand plan, and Lear fights to help Elizabeth before it's too late.

As Amy experiences symptoms of the virus that indicate she is close to turning, Brad brings everyone together, and Lila and Sykes race to perfect an anti-viral medicine to save her from Fanning. Meanwhile, Richards tries to keep Project NOAH contained when Guilder makes a mysterious decision to let go of most of the staff while also trying to ward off Babcock's attempts to get in his head.

When the only way to stop Fanning and the virals' escape from Project NOAH involves a dangerous explosion that could leave Brad, Sykes, and the cure for the virus caught in the crossfire, Amy must be the one to decide what's best for humanity. In the wake of this, surprising alliances form and a key figure returns to instill confidence, convincing everyone to fight for their lives.
