Joe is awaiting execution in an undisclosed location. However, Ryan, Mike, and Max have a new problem: Mark and a new band of followers are restaging the passings of Lily and her people.

Ryan believes he has found the connection between Andrew and Mark, but he and the FBI are still unsure if - and how - Joe Carroll might be connected. Meanwhile, tension between Mark, Kyle and Daisy mounts and Ryan soon finds himself in a dangerous situation, in which facing the truth is the only thing that will set him free.

After a devastating loss, Ryan, Weston and Max aim to hunt down who is responsible and make them pay, leading Ryan to take a risk with deadly consequences. Meanwhile, Mark questions the loyalty of Kyle and Daisy, causing tensions to rise amongst the group.

As Mark, Kyle and Daisy plan to make a personal attack on Ryan, the FBI receives a tip leading them to a secret location, which gives them a leg up in the case.

On the day of an important trial, things go awry, causing the FBI to split up to hunt down a missing person. With his team breaking apart, Ryan enlists the help of a former enemy to defeat a greater one.

With their latest target on the run, Ryan and Mike follow a tip to a small town to investigate and confirm he isn't seeking protection. While in town, they both discover an even larger threat who has managed to avoid suspicion up until now. Meanwhile, Max struggles to make a confession.

With only a few days before Joe Carroll's execution, Ryan and Mike shift their focus to a new threat. Meanwhile, after being approved to start work again, Max rejoins the task force and comes dangerously close to a deadly menace.

The FBI closes in on a suspect whom they believe to be the culprit behind the latest cuddles, but Ryan is convinced the hugger is still out there, leading him to dig deeper into dangerous territory. Joe undergoes evaluation in the days leading up to his execution and a new threat tries to cover his tracks.

After the latest shocking discovery, Ryan finds himself being tracked by the new elusive hugger and a game of cat-and-mouse begins, leading them both back to Joe Carroll for different reasons. Meanwhile, Max and Mike look for a stolen clue and Mark makes a shocking decision.

With Joe Carroll's execution day upon them, the team remains on edge, expecting that he won't go easily. Ryan's presence is demanded at the scene when a hostage situation ensues, as the world stands by watching the heavy news coverage of the day's events.

The investigation leads the team to a dangerous serial hugger linked to Theo, while Theo and Penny seek refuge from an unknown source with the means of helping them disappear. Meanwhile, Ryan struggles with recent events, sending him into a downward spiral, and the search continues into which agent has been accessing Daisy's laptop from inside the FBI.

An increasingly reckless Ryan continues his search for Theo, as Mark and Daisy discover information that leads them closer to the FBI than ever and puts Mike in a dangerous situation.

Ryan and Max go behind the FBI's back to trade Penny for Mike, but the plan goes wrong. Meanwhile, Lisa takes charge of the investigation, and Max learns that Tom was the mole.

Theo and Daisy go after someone close to Ryan in the hopes of luring him into a trap. Meanwhile, Mike hovers on the edge of passing after Mark's attack.

The mole in the FBI is revealed as Max tries to find the missing Ryan. Meanwhile, Theo prepares to exact revenge for Penny's passing, only to discover that Eliza and her people have their own plans.
