Cued by the popular "The Librarian" trilogy, this series introduces new members of an ancient group protecting mystical artifacts. Hidden below the Metropolitan Public Library, the secret society's longtime leader is Flynn Carsen, whose job has become very complicated. To help, the Library recruits Eve, a counterterrorism agent responsible for organizational security; Jacob, who has encyclopedic knowledge of art, architecture and history; Cassandra, who links auditory/sensory hallucinations to memory; and Ezekiel, a skilled thief and master technician. Overseeing them is Jenkins, the reclusive caretaker of the Library's sleepy little annex in Oregon. Noah Wyle executive produces and recurs as Flynn, the role he played in the movie series.

The balance of the universe is put in jeopardy when the Monkey King's sacred homeland of Shangri-La is taken over by a ruthless collector of magical artifacts.

The library is simultaneously infiltrated by DOSA and Apep; Flynn, Baird, Stone, Cassandra, Ezekiel and Jenkins must put aside their differences to save the library, the world and themselves.

A secret sect of the Vatican Church unearths a map detailing the locations of the four cornerstones of the Library of Alexandria; Flynn and the Librarians work with an unexpected ally to stop them before the stones can be used to destroy the Library.

When people begin getting hurt in the unluckiest of ways, the Librarians follow the trail to a casino where the owner appears to possess an artifact capable of stealing people's luck.
