Koos is having a difficult time finding work and finances in the Dobbelsteen household are getting a bit tight. Wiep gets a part-time job modeling swimwear and insists on taking Dr. John out to expensive restaurant 'La Cloche'.
Mien tricks Koos into help cleaning Lydie's mother's house on the eve of her return from Canada. When grandma does arrive, she does so carrying the wrong suitcase, which is filled to the brim with sexy underwear.
Mien gets to know Neighbor Buys a little better because of some wrongly delivered letters. She also misunderstands Dr. John's relationship to a patient and invites Koos over for lunch at the Doctor's for a big surprise.
Lydie and John have both noticed that drugs are missing from the medicine cabinet. The police advises to install an alarm and to keep this a secret from as many people as possible. Mien is burning with curiosity when Koos is asked to install the device and she's not allowed to know what it is.
Jopie & Annie surprise Koos & Mien with a weekend away. As Mien had just made a large pot of soup for the entire weekend, she gives it to Lydie and Hans. But they are also going away so the pot keeps changing hands...
Wieps birthday is approaching fast and both Lydie & Hans and Dr. John buy her an etching press without the other party's knowledge. However, the transport service is only able to deliver one at a time.
