Jens Lehnert sends his grumpy consultancy partner and key employee Carla Schneider to audit the old-fashioned mint farming of a collective in Saxony. In an attempt to coax a probably negative report, unwitting the assessor is female, she's lodged with its director Simon Vorberg and his charming family, but it alas starts on a frightening tone. Gradually, she's charmed by the village and especially the Vorbergs, alas unlike the enterprise, yet is inspired by the inventive villagers' fair stalls.

With a woof-woof here and a baaa-baaa there and a quack-quack, oink-oink everywhere, there's always some furry or feathered creature demanding attention from the Hansens. It's partly because Dr. Philipp Hansen is a veterinarian who's just opened a practice in the big old villa he's moved into with his family. But it's mostly because of ten-year-old daughter Greta, who never saw an animal she didn't want to adopt.
