Season one drags Ryan back into a world of horror, when the FBI reaches out to him in the wake of serial killer Joe Carroll’s escape from death row. Challenged with an ever-growing web of murders, Ryan and the FBI soon discovered they were up against not one killer, but a cult of killers directed by Joe.

As season two unfolds, Ryan, FBI Agent Mike Weston and Ryan’s niece, NYPD officer Max Hardy, lead an off-the-books investigation into Joe’s presumed death and the whereabouts of his cult’s remaining members.

In season three, Ryan, for the first time ever, begins to suspect that his greatest enemy, the man responsible for an endless list of atrocities, may not be the biggest foe he’ll face – in fact, Joe just might be a prelude to horror he’s never imagined.
