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.

When students begin disappearing at Wexler College, the librarians head out to investigate; Cassandra gets an offer that is difficult to turn down.

The librarians' first solo mission hits a snag when Baird loses the others in a mysterious labyrinth that magically exists below the skyscraper of a modern corporation.

Flynn is kidnapped by a mysterious stranger with both amnesia and a collection of the library's missing artifacts; the group pursues the Staff of Zarathustra.

When the Serpent Brotherhood wants to kill Santa, the librarians must rescue him and help him accomplish the secret purpose of Christmas.
