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.

Santa takes Flynn, Baird and Jenkins on his first vacation in centuries; the Librarians use Santa's sleigh to save Ezekiel's career-criminal mother, as well as Christmas itself, from Santa's grinch of a brother, the Patron Saint of Thieves.

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.

Drawn into the world of Baird's favorite film noir movie, the Librarians must perfect their skills in lassoing, sharpshooting and snappy dialogue to make it out alive.

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