After getting back from vacation, Recker finds himself with not much to do. With work in the city at an all-time low, Recker is approached by a familiar face. Michelle Lawson has a job for him in regards to an illegal arms dealer that has continuously given the CIA the slip. Feeling like he can trust her and work for the agency again for one job, Recker agrees to do the assignment once all his conditions are met.

With Jones and Haley on board, the teams heads off to London to find their target. It's back to where everything started for Recker when the CIA initially tried to terminate him. But what they hope is a short-term assignment turns into a much longer stay, and with Mia having problems of her own at home, Recker turns to old friends in order to help him accomplish his mission and get home faster.
