The whole family is going on a skiing holiday in Norway when Dad breaks his leg. So Uncle Erik takes the five oldest children. On the ferry, Amalie meets ski instructor Dan, and Uncle Erik gets very seasick. It turns out that Dad has rented a very small, leaky cabin, but Jan and Michael sort it out so they can move into a large suite. It turns out that it has been rented to Mrs. Flinth and her friends, and she causes a lot of trouble. The family is thrown out, but once again Jan and Michael fix the situation. They claim that Erik Lund is a famous singer. Erik is busy looking after Amalie, but when she discovers Dan's flirting with another girl, she gets the boys to help her. Meanwhile, Erik also finds time to go ice skating with Mrs. Flint.

Three siblings ingeniously avoid being sent off to a children's home while their solo-mother serves a short sentence in a prison for shoplifting. Rather than have the news leak out and have to be escorted off with the eccentric welfare officer, they invent a 'never present' dad who is looking after them.

Five young siblings deal with a reluctant chaperone when they wind up stranded on a trip to Egypt.
