Christmas in Rotnebu

The Dyhre Olstad family has rented a cabin in Finnskogen near the small village of Rotnebu. They’re going to spend four cozy pre-Christmas days here... or so they think. Soon, mysterious things start happening. Objects disappear, and strange noises are heard at night. Something isn't right, and siblings Kriss and Nils set out to solve the mysteries.

On the last day of the trip, the car won't start. The family has to go to Rotnebu for help—but the villagers of Rotnebu are odd. They don't seem to understand the concept of "Christmas", and they're not very helpful either. More and more mishaps force the family to stay in Rotnebu, and Kriss and Nils have to solve new mysteries every day.
