A Librarian -- a custodian of a magical repository of the world's most powerful and dangerous supernatural artifacts -- from the past travels to the present and finds himself unable to return to his own time. When he returns to his castle, which is now a museum, he inadvertently releases magic across the continent. In order to set things right, he is given a new team of Librarians to help him clean up the mess he made.
Half of the Librarian team gets trapped on a runaway ghost train; can the rest of the team help in solving the unresolved business of the ghosts on board before the train completes a rampage of destruction?
The Librarians head to Paris after a string of robberies leaves mysteriously lovestruck victims in their wake; when they learn that a magical love artifact is behind the thefts, they enlist help from Vikram's old friend, Cupid himself.
The team goes to a college campus with a world-class observatory to discover who is using the Crystal of Dr. John Dee to steal people's memories, in order to own the future.
When the magic door reroutes Charlie, Lysa and Connor to a bizarre manor where a series of Agatha Christie-style murders take place, they must figure out whodunit, while Vikram tries to track them down with the help of a mysterious tarot card reader.
