Children
Rosa and her big brother Eske are to spend the summer with their cousin Karl Otto and cousin Molly, on a large farm that father Lasse is in the process of setting up. The children explore the dark ceiling and find a mysterious chair. A talking chair which calls itself Babylon - the world's most difficult game. The children's summer has now been saved, but it is important not to say anything to the adults, because you do not have to play your (summer) days away. But as the kids begin to play the enigmatic game that no one has ever completed, mysterious things begin to happen on the farm.
