It’s graduation day for the NATS of Quantico, while, in the future, Alex and her team find themselves head-to-head with the terrorist.

While investigating the dark world of espionage at a mysterious CIA training facility, Alex becomes caught at the center of a conspiracy that threatens lives across the globe.

The trainees are put through a training drill that tests their stress levels while Alex tries to gather information and get close to Owen. Meanwhile, in the future, the terrorist organization demands a trade, a move that could possibly end the stand-off.

The recruits learn how to burn everything down if they are ever exposed. Meanwhile, a mysterious death leads to an FBI investigation at the Farm. In the future, Alex heads back into the crisis zone and exposes the true traitor within the CIA.

In the wake of the G20 hostage crisis, President Claire Haas assembles an illegal and clandestine joint task force, bringing together Alex and her friends from both the FBI and CIA to unmask a global conspiracy.

Risking it all, Alex works with Owen to infiltrate the Collaborators. When they begin to test her loyalty, Alex realizes she’s become a pawn in their plan to take down both the President and the task force.

After an impossible choice is made, a flood of new proposals shine a light on the final stages of the Collaborators’ plan. Fractured but not defeated, the task force, with the help of some old friends, work to put the pieces together before the Collaborators can enact an unthinkable terrorist attack.
