When Maggie gets locked in the car, Marge frantically tries to find the spare keys, but is unable to do so because they have so many, they find that they have a key for practically every door in Springfield, Lisa finds an unused classroom in the school, which Lisa questions about. It is eventually covered up, but Lisa is determined to find the source of the mystery by breaking the prop bookshelf and discovering someone write "The Children are on Bus 23".
To find out more, Bart and Lisa consult with Nelson who tells them that Bus 23 was supposed to make a journey across an ice bridge but never made it back. Bart and Lisa ask Homer to fly (who had recently stolen the Duff Blimp) over where the ice bridge would be and find the sunken bus 23. Inside she finds a number of manikins.
