S4, E4: Baird and Flynn take a rare night off to go on a date and head to a revival theatre where one of Baird's favourite film noirs is playing. They're settling into a classic yarn when, they find themselves trapped within the movie! The Librarians wonder where their teammates have gotten off to, and they wind up on the case. Of course, there must be an artifact involved, but first and foremost this is a rescue mission. Stone, Ezekiel, and Cassandra attempt to use the door to get into Baird and Flynn's noir, but it malfunctions and sends them off to B-Movies playing elsewhere in the theatre!
