 | This section's plot summary may be too long or excessively detailed.(December 2020) |
Kyle Keeley is an imaginative young boy who loves to solve puzzles created by famous game designer Mr. Luigi Lemoncello. One day, Lemoncello unveils his newest creation: a high tech library in which he selects twelve young children to solve puzzles and riddles and whoever gets out first will be the new spokesperson for all things Lemoncello.
The twelve are selected: Kyle, his adventurous best friend Akimi, bookworm Sierra, nerd Andrew Peckleman bully Charles Chiltington, popular girl Haley Daley, Rose Vermette, helpful Miguel Fernandez , Yasmeen Smith-Snyder, over-eager Kayla Carson, Sean Keegan, and Bridgette Wadge.
Upon entering the library, Lemoncello and his assistant Dr. Zinchenko explain how difficult it is going to be and that they can use the devices they are given to opt out which opens a trap door that takes them out of the library. This causes Bridgette and Sean to forfeit and go home. Afterwards, the rules are explained and they are all given a library card which Kayla takes and hits causing her to be eliminated since she did not listen to the rules. After that, the challenge begins.
Upon solving the first clue, Chiltington reveals his sly and bullying self when he lies to Yasmeen causing her to be eliminated. Afterwards, they are given four rooms designed based on book genres: horror, fantasy, classic, and children. A holographic librarian named Ms. Tobin appears and explains the rules of entering the room including you can only enter each room once.
Miguel eagerly offers to enter the horror room to get the clue, but he soon becomes terrified by Count Dracula and Frankenstein's monster and opts out before he can reach The Tell-Tale Heart . Chiltington also gets Rose to opt out due to her own fear. Getting fed up with one another, the six remaining children divide into two teams: on one is Chiltington, Haley, and Andrew and on the other one is Kyle, Akimi, and Sierra. While Kyle's team enters the classic room where they had to ride flying books to solve a clue, Chiltington's team enters the children's section where Chiltington works to put Humpty Dumpty together while Peckleman meets Charlotte from Charlotte's Web and Mother Goose. Both respective teams manage to receive their clues although Chiltington lies to everyone he forgot the clue in the children's section. This causes Haley to attempt to get it back, but is disqualified by Ms. Tobin for trying to go back inside: a rule which she did not listen to due to her doing selfies which Ms. Tobin is familiar with. She is sent down the trap door and is deposited outside as the crowd laughs at her. Lemoncello talks to Dr. Z about Chiltington's trickeries as Dr. Z leaves to go deal with a glitch involving Wilbur the Pig.
As Dr. Z makes her way to the scene of the glitch and runs into them, Chiltington and Peckleman state that they aren't cheating as Chiltington secretly takes a golden key which has power over the whole library. Kyle's team enters the fantasy section while Chiltington decides to cheat and gets Andrew to follow him into the section as well deciding to cheat and use them to get the clue which Andrew is uneasy about. The troll from Three Billy Goats Gruff has them make out as many words from Lemoncello where the failure will have them be attacked by the giant from Jack and the Beanstalk . Kyle's team solves another riddle and receives a clue. While using the key to collapse the beanstalk and cause the Wicked Witch of the East to manifest, Chiltington however accidentally destroys the system releasing all the creatures including Count Dracula, Frankenstein's Monster, the troll, and a werewolf into the library and wrecks havoc.
Lemoncello decides to go into the library and help the children. While Mother Goose is shown to have gone over to one of the library sections and brushed up on ninjitsu as mentioned by Charlotte, the kids were able to use the characters' weaknesses like water on the Wicked Witch of the East. Chiltington, regretting what he has done after he and Peckleman were attacked by Hansel and Gretel for eating their bread crumbs, also elects to help the team. The group escapes into the vents as they see the giant approaching the exit to the fantasy section.
Using dynamite, Lemoncello was able to put some distances between them and the pursuing Count Dracula, Frankenstein's monster, werewolf, and Hansel and Gretel. Making it to the exit, Ms. Tobin tells them how to activate it after she had fought off the troll. They all manage to restore order until a giant pterodactyl appears. The dinosaur was an idea created by Kyle and was released in the idea room when the children had previously entered. Instead of running in terror, Kyle faces his fear and fight off the dinosaur with red balloons he found after Lemoncello tells him not to blame himself for his idea, but embrace it as his own and defeat it using his bravery.
Lemoncello, Dr. Z, and the five remaining children exit the game and Lemoncello, impressed by their bravery and creative solutions, declare them all winners and thus spokespeople for his company. Dr. Z states to Lemoncello that she will need a vacation after this as well as getting the book characters back into their respective sections. Peckleman offers Chiltington his friendship and a ride home after having been previously told that Chiltington's parents could not be here due to work. Lemoncello offers Kyle a job as a summer librarian which he happily agrees to and then, Lemoncello presents Kyle his golden key to hold on to for safe keeping.
