Koninklijk Theater Kiekoet plays a family show for children aged 5 and over and their (grand)parents.
Prins Didier de Stoere de Zesde tries to save his palace when his mother, Queen Petunia, decides to sell it because of many debts. Didier comes up with various plans and even wants to go to work, but Petunia thinks that a prince shouldn't work. When buyers arrive, Didier discovers they are not trustworthy. He tries to stop them, but is magically turned invisible for it. In the end, everything turns out fine: his father, Diederik de Stoere de Vijfde, turns out to be smarter and kinder than expected, allowing Didier to get his way and continue living in the palace.
