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.
The episode begins with a montage of how Liam orchestrated the entire terrorist plot to frame Alex. In Quantico, the NATs are preparing to graduate. After Alex realizes that Ryan lied about his work assignment, she breaks off their relationship again. Meanwhile, Shelby, still upset at Caleb for ruining her chance at bringing her parents to justice, sabotages him by telling his mother his goings-on. In the present timeline, Ryan discovers that Miranda was being watched, which does not line up with their explanation for everything. After visiting Liam's home, Alex discovers that "The Voice" is Liam, who has kidnapped both Ryan and Miranda and has taken them back to Quantico, where he plans to detonate the nuclear bomb. When they arrive there, Liam explains his motives and Alex and Ryan manage to kill him. After the team discovers that the bomb cannot be stopped, Simon sacrifices himself by letting the bomb detonate in a lake, killing himself but saving countless lives. At Simon's funeral, Alex tells Claire that she knows Claire helped Liam. Two months later, after she leaves the FBI, Alex is approached by a man named Matthew Keyes who offers her a position in the CIA.
