Emily is serving out the final days of her FBI suspension while struggling to come to terms with the consequences of her actions from the last two seasons. Hyper-vigilant and distrusting of others, Emily sees threats everywhere and takes a closer look at everyone.

Following the deadly events, Emily must race against time to find and save Nick, with the help of his mysterious informant, Kai. Upon tracking his location, Emily realizes there is a more complex conspiracy afoot and is left to grapple with the possibility that Nick has been killed.

Disoriented and drugged into a paralytic state, Nick wakes up in a dark and confined location. Meanwhile, without a body as proof, Emily refuses to accept that Nick is dead and makes a deal to get him back, only to find that Dawkins has laid a trap and everyone is in danger.

Emily’s demand for the FBI to go after Nick is met with resistance, which leads her to set in motion a risky plan that puts her face-to-face with the one man who can lead her to Nick. Meanwhile somewhere in Europe, Nick is being drugged and psychologically tortured, revealing his buried guilt and his insecurities as an FBI agent, a husband, and as a father.

Emily complies with Dawkins requests in order to be taken to Nick, and orchestrates a clever ruse along the way. Meanwhile, as Nick’s guilt and paranoia threaten to overwhelm him, he finally puts a rest to the personal demons that have haunted him.

Emily makes a final attempt to trade the stolen files for Nick and demands proof that he is alive, unaware that Nick has escaped from his captors in a thrilling chase. Nick makes contact with the FBI, and Emily makes a bold decision to confront Cal about his past.
