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.

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.

Nick continues to be tortured but finds an opportunity to try to escape from his captors. Cal and Emily head off to rescue Nick and become closer along the way. When they reach the mysterious location, they find evidence that links to Nick’s case back in Boston, but there’s no sign of Nick.

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.
