The Librarians - Season 4 (DVD)

In this season of The Librarians, our heroes embark on new, action-packed adventures, risking their lives once again to save the world.

They face off against Santa's brother the Patron Saint of Thieves, try to save a town plagued by ghosts from the Civil War, battle a casino that steals luck, and endure a body switching fiasco. But, their greatest challenge will come from within the Library itself.

With Charlene no longer tethered to the Library, which keeps it grounded to humanity, one Librarian and one Guardian must step up and take the mantle. As Jenkins organizes the Tethering Ceremony, the high ritual that will bond the pair to the Library forever, thus granting them immortality, Flynn and Baird seem poised to make this sacrifice. Until a woman from Flynn's past reveals herself to be one of the Library's dirty little secrets.

Confronted with a dark mystery about the Library, every Librarian must ask themselves some tough questions: Is the Library itself good or evil? After millennia of one Librarian at a time, is it dangerous to have multiple Librarians working together? Can a Librarian ever live a normal life filled with love, friends and family? The Librarians have a lot of research to do, but this time, they'll need to find the answers inside themselves without any books or prophecies.
