Season 04, Episode 20 – The Debt Collector
Liz becomes the target of a mercenary known as the Debt Collector, so Red turns to an unlikely source for help. Meanwhile, Ressler faces an unexpected complication in his efforts to stay ahead of Agent Gale’s investigation.
Raymond “Red” Reddington, one of the FBI’s most wanted fugitives, surrenders in person at FBI Headquarters in Washington, D.C. He claims that he and the FBI have the same interests: bringing down dangerous criminals and terrorists. In the last two decades, he’s made a list of criminals and terrorists that matter the most but the FBI cannot find because it does not know they exist. Reddington calls this “The Blacklist”. Reddington will co-operate, but insists that he will speak only to Elizabeth Keen, a rookie FBI profiler.
