Because of a misunderstanding, Plop turns into the new king! Klus, Kwebbel and Lui move to the palace, while Plop is trained to become royalty, but what happened to the real heir of the throne?

It does not go well with the Romeo's. Especially Chris gets on his hips when Davy once again show up late to a concert where other singers are on the bill. When one of the artists will be attacked just before his performance, Davy intervenes. Chris and Gunther are amazed at his intervention and demand an explanation. Davy takes them to his house and shows how he's been a undercover agent within the HIT mission. More he can not lose on this.
