Season 4
The Librarians centers on an ancient organisation dedicated to protecting an unknowing world from the secret, magical reality hidden all around.
Rebecca Romijn, Christian Kane, Lindy Booth, John Harlan and Noah Wyle return for the fourth season of the fantasy adventure, kicking off with a special feature-length, Christmas-themed episode in which our heroes do battle against Santa's brother, the Patron Saint of Thieves.
This season will see the team try to save a town plagued by ghosts from the Civil War, battle a casino that steals luck from its unfortunate patrons, endure embarrassing body switching fiascos and join forces with a time-travelling Librarian from the past.
In the first episode of Season 4: when a secret sect of the Vatican Church unearths an ancient map detailing the locations of the four cornerstones of the Library of Alexandria (the original Library), it's up to Flynn and the Librarians - with the help of an unexpected ally - to stop them before the stones can be used to destroy the Library.
