The school cafeteria may smell like tater tots and sloppy joes, but the secret crime-fighting Lunch Lady has sniffed out something truly rotten brewing down the hall. A dark cloud has settled over the school library, and it is up to her to find out why. The school's usually cheerful and helpful librarians have suddenly become cold, strict, and incredibly secretive. Even Dee, the friendliest member of the Breakfast Bunch, cannot manage to get a single smile out of them. Something highly suspicious is happening behind the tall bookshelves. It turns out the librarians have formed a secret league with a terrible mission: they want to completely destroy a massive shipment of brand-new video games before the students can play them. With her incredible gadgets and the Breakfast Bunch serving as backup, the Lunch Lady is ready to serve up justice and save the games.
