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 world is morphed into an unrecognizable place where the library never existed; Baird brings the librarians together in an attempt to prevent the bleak, new world from becoming the new reality.

Someone is killing off potential Librarians, and it's up to Flynn Carsen and his new Guardian, Colonel Eve Baird, to save the three that are left.

The Serpent Brotherhood is trying to return magic to the world; Flynn, Colonel Baird, and the potential Librarians must stop them before it's too late.

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.
