An imprisoned Nozem is visited by the Baroness. She has half a treasure map in her possession and recruits him to help her find the other half. Meanwhile, it is found by Paulien Wijnstra and she calls for her famous neighbors Hielke and Sietse Klinkhamer. Along with their best buddies Kees Dijkstra and Louw Vrolijk they also go on a quest. But after a fight with the Nozem, they lose their half of the map and now have to figure out a plan before he and the Baroness get to the treasure first.
