Denmark, 2014. A former police officer asks Carl Mørck, head of Department Q, to find out who brutally killed his young twins in 1994. Although a local inhabitant confessed and was convicted of murder, Carl and his partner Assad soon realize that there is something in the case resolution that is terribly wrong.
In search of a new lifestyle, Johannes and his wife Pernille leave the city and move with their two children to Johannes’ childhood town in the country. When Johannes’ drunken brother Lars accidently runs over Anna, a local, and plants false evidence pointing at the emigrant Alain, Johannes stands up to defend Alain. But it comes with a price.
This time, the children's parents have gone on vacation to New York, and it is up to Uncle Erik to take responsibility for his nephews and nieces, or at least try to. Everything seems to be going well, until Jan and Michael take a little drive in their father's new sports car. The mechanic's bill comes to $30,000, so the children persuade their uncle to open a hotel in their own house. The hotel quickly fills up, but not all of the guests are easy to please. And the strict Mrs. Flinth is definitely not happy with the children's successful hotel business!
