Georgette Muys, Vicky's mother, plans her revenge on Stavros and Rik. As head of the building department of the city, she exorbitantly fines Rik for having built a dependence without plan or consent : Stavros' barber shop. He can either tear it down, or submit a request to have it regularized. The request, however, will land with Mrs Muys, and she makes it abundantly clear to Rik she will refuse the request and fine him tens of thousands of Francs. Mrs Muys has also discovered that, despite her forbidding Vicky to see Rikki, the two have still been meeting and exchanging love notes. She takes steps to prevent it from happening again and Rikki is at his wits' end. Ida takes a hand and enters Jef in the gymnastics club where Vicky also trains. He is to be the "Postillon d'amour". Mrs Muys finds, out, but gets locked in with Jef. When her husband and Ida arrive looking for the two, they find them in a rather compromising situation, giving Rik the opportunity to put some pressure on his affair. Mr Muys also takes a hand, and the two love birds can see each other again.
