Dr. Hansen still doesn't have any patients, and his daughters are getting worried, too. Is there anything they can do to help? Meanwhile, he finally meets Jonas's family.

Oswald the dog is ill and Jonas is very worried about him. While his father is getting ready to put Oswald out of his misery, Jonas seeks help from the new vet in town.

While their parents are busy getting the house ready, Lilie and Greta go shopping and have their first experiences with the villagers. Greta doesn't exactly receive a warm welcome at school, but there is someone who stands up for her!

Dr. Hansen decides to drive to the village to get the key. At the same time, Jonas sets off to deliver the key to the new vet family, along with a cake as a welcome gift.
