Dik Trom and his friends are on vacation and having a great time. They come up with all sorts of things to do to pass the time. They go fishing, make wooden carts, shoot bows and arrows, and get up to all sorts of mischief. Even Constable Flipse is not safe from their pranks. They are having so much fun that no one, not even a bully, can spoil it. They hope that they will experience something exciting during this vacation. Suddenly, they find a haunted house. Will that be scary enough?

Dik Trom hears that Oude Kee no longer has any money to buy food. Dik and his friends decide to help her and collect money for a small organ with which she can earn a living. They also give her some money, but it is stolen by Oude Kee's cousin. Dik wouldn't be Dik if he didn't catch the rascal after many exciting chases.
