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 deaths of Lily and her people.
Mark, Daisy, and Kyle go after someone close to Ryan in an attempt to force him, Mike, and Max to confess to their killings of Lily and the others. Meanwhile, Ryan discovers a connection between Joe and Andrew, and goes to confirm it with an unexpected source.
Ryan and his team go looking for the man responsible for Jeff's death, a trail that leads Ryan to an old friend. Meanwhile, Mark abducts two reporters, unaware that his actions are interfering with Daisy and Kyle's secret plan.
Mark, Kyle, and Daisy kill four firemen, and then go after a college student. Ryan soon realizes that the entire thing is a ploy to undermine the case against Strauss, who is going on trial for his crimes.
Ryan's credibility at Strauss' trial is undermined by the accusations against him. Meanwhile, Kyle and Daisy go after Carrie Cooke, and Mike comes face to face with Mark.
Ryan turns to Joe for help, and the killer's advice leads them to Beacon, NY. Strauss and Daisy take refuge with one of Strauss' students, waiting for another student to arrive with the fake IDs that Strauss needs to leave the country.
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.
