1990 film directed by Martin Asphaug

The entire extended family is happily on its way to a nostalgic Christmas at a rented cabin in the mountains. The cabin becomes cramped, however, when mom and dad and four grown-up children with their respective families, a dog and in-laws from Poland squeeze inside the frozen cabin walls in 30-below-zero weather.

One day, just before Christmas in 1942, Gerda's and Otto's parents are arrested for being part of the Norwegian resistance movement during the Second World War, leaving the siblings on their own. Following the arrest, they discover two Jewish children, Sarah and Daniel, hidden in a secret cupboard in their basement at home. It is now up to Gerda and Otto to finish what their parents started: To help Sarah and Daniel flee from the Nazis cross the border to neutral Sweden and reunite them with their parents.
