Ella and her friends find out that their much-loved neighborhood school will be shut down, and all the kids will be relocated to a brand new central school – err, sorry, not simply a school, but something much fancier: a Centralized Learning and Schooling Facility located in the city center. They soon find out that the most popular kid in the new facility, Ef One, is to blame for their misery. Or, to be more precise, his insanely rich father is. Ella and her friends decide to team up with the teacher to fight for their old school... Based on Timo Parvela's "Ella-series" – the most popular children's books in Finland.
