The princesses of Prinsessia are invited to do the opening dance at the annual Prinsendaal ball. A great honor, because Prinsendaal is the oldest and most important prince school in the country. Miss Flora urges the princesses to behave in a neat and orderly manner. After all, she wants to make a good impression with Prinsessia. That is not easy, because the head of Prinsendaal wants nothing less than a perfect opening dance. The only thing that counts for him is order and discipline. A big contrast against the colorful, playful princesses Violet, Roos, Madeliefje, Iris and Linde.
