The film follows the spirited press photographer Jo Markus (played by Denise De Weerdt), who works for an Antwerp weekly magazine. Nicknamed "The Princess" because of her aristocratic mother, she teams up with two bumbling friends (De Woodpeckers, Jef and Cois Cassiers) to not only bring a gang of thieves to justice but also discover love along the way..
