The Librarians is an American fantasy-adventure television series developed by John Rogers that is broadcast on TNT, and premiered on December 7, 2014. It is a direct spin-off of The Librarian film series, sharing continuity with the films. On January 24, 2017, TNT renewed the series for a fourth season, which premiered on December 13, 2017.
The series follows four people, Eve Baird (Rebecca Romijn), who is chosen by the Library to be the new Guardian, as well as Ezekiel, Cassandra and Jacob, who were asked to apply to the Library to become The Librarian, but for some reason didn't show up to the "auditions". In their place, the current Librarian Flynn Carsen (Noah Wyle) is searching for the Library (which is lost in time and space during the pilot). The four become a new team of Librarians in order to solve impossible mysteries, recover powerful artifacts, and fight against supernatural threats, especially the forces of the Serpent Brotherhood, led by the mysterious immortal Dulaque (Matt Frewer).
