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.
