On the day after the Great Storm, there is suddenly a new building in the middle of Kraaidorp.
The Dark School it is called, a boarding school for all the children living in Kraaidorp.

Even his father and his best friends firmly believe that Bertus and Colette Zwart, the school principals, mean well.

But then, one by one, the children disappear.
