While on an excursion in the mountains, aging natural scientist, Professor Karker, discovers an idyllic valley. Here, he meets a farmer’s wife, Aase, and her two adult children: the kind-hearted Kavli and his sister Kari, who is a breath of fresh air. Back home, Karker sends his own two spoiled and self-indulgent representatives of modern youth, Thor and Synnøve, on a re-education trip to visit his new friends in Sunshine Valley. This sets in motion an entertaining and beautifully filmed comedy.
The outdoor scenes were filmed in Telemarken and Gudbrandsdalen in Norway. The train station scene was filmed at 'Sjoa Stasjon' which still exists today and hasn't changed much. The film has Danish intertitles and English subtitles.
