Video: THE LIBRARIANS: THE NEXT CHAPTER Season Finale Clip

TNT has shared a sneak peek clip from the season finale of “The Librarians: The Next Chapter,” executive produced by Dean Devlin. In the finale, General Gregor retrieves the Sword of Mars and uses it to take over the country of Caucasylvia (remember from the Train episode), and gains control of their nuclear arsenal. The team must steal the Sword to prevent world calamity.

A spinoff of the acclaimed original TV and film franchise, the twelfth episode will debut on Monday, August 4 at 9pm/8pm Central on TNT.

Produced by Electric Entertainment, “The Librarians: The Next Chapter" centers on Vikram Chamberlain (Callum McGowan), a “Librarian” from the past who time traveled from 1847 and now finds himself stuck in the present. When Vikram returns to his castle in Belgrade, Serbia and discovers that it is now a museum, he inadvertently releases magic across the continent.

With the help of a new team of eclectic heroes, including a savant in world history, a scientific genius, and a highly skilled Guardian, Vikram has only six months to clean up the mess he made. Throughout the season, the team will embark on fantastical adventures, including a surprise reroute to a manor where Agatha Christie-styled murders take place, a time-travel back to the days of KING Arthur at Camelot and even an encounter with the first-ever vampire. 

The 12-part series stars McGowan (Jamestown), Jessica Green (The Outpost), Olivia Morris (Hotel Portofino) and Bluey Robinson (Britannia). Caroline Loncq (Mammals) guest stars. Christian Kane will reprise his role as “Jacob Stone” in a Guest Starring role. Dean Devlin serves as showrunner and executive producer alongside Marc Roskin and Rachel Olschan-Wilson of Electric Entertainment. Noah Wyle serves as producer. Mark Franco of Electric Entertainment and Jonathan English of Balkanic Media also produce.
