The Librarians travel to a town where fairy tales are coming to life - and attacking.

When a group of competitive high-school students start undercutting each other with witchcraft, the Librarians have to intercede before disaster destroys them all.

Students start disappearing at Wexler College, an institution started by a mad historian/architect who believed in alternate dimensions. When the Librarians arrive, they discover a young student from the physics department is investigating the bizarre occurrences on her own. Meanwhile, Cassandra gets an offer that's difficult to turn down.

A routine artifact retrieval is anything but when the artifact grafts itself to Cassandra. Meanwhile a blizzard forces Stone and Cassandra to take shelter at a mysterious hotel that is hosting a demon convention, who want the artifact for themselves.

A rash of people spontaneously combusting leads the Librarians to a holistic spa run by vampires, who have discovered the secret to walking in the sun.

After Cassandra freezes up during a mission, she decides it's past time to go on a vacation. Searching for her ideal town, she lands on Havenport, the "Safest Town in America." At first blush, it seems just what she needed.

After the world is morphed into a horrible and unrecognizable place – one where the Library never existed – it's up to Baird to bring the Librarians together before this bleak, knowledge-less world becomes the new reality.
