When Red goes on the hunt for a legendary treasure, he draws the attention of Abraham Stern, a cunning manipulator who has devoted his life - and the lives of many innocents - to recovering the fortune that is his birthright. Meanwhile, Liz's quest sends her down a dark path, leading her to study the methods of one of the Blacklist's most dangerous criminals.

When bodies are discovered in abandoned woods, Red points the Task Force toward The Invisible Hand, a group that targets those whose actions are morally reprehensible yet fully legal. Meanwhile, Red steps in to assist one of his employees, and Liz discovers a major clue about Tom's investigation.
