For over five years, Piper has been known as the town where children vanish at night. When five more children are taken away by the same mysterious force, they find themselves in a fantasy world called Kindergarten where there are no adults, and they can be whatever they want to be.
The only person who seems to know anything about the new world is Alicia's brother, Charlie who soon after arriving suddenly leaves them to fend for themselves. Alicia and the others go looking for Charlie in order to find a way to get back home. But the further they go into the strange land, the more its addictive nature makes it harder for them to want to go back.
