Tiny Per gets its biggest wish: He becomes a scout. Sister also gets hers biggest wish: She's getting married. So now Mie take over the household and it's not going to go quietly.
At home in the small family is nothing new. Tiny Per is the school's mischief maker, Sister has heartaches, Mie and Ole has to be in the school play, etc. But suddenly something happens. Good old Uncle Anders has a twin brother in the United States. He called Sofus, and now he comes home to celebrate 70th birthday. He was a troublemaker when he left and now he has become even worse
Lilleper is starting school, and on the last day of summer vacation, his father invites the whole family to a party at Tivoli. But then everything goes wrong. Per doesn't like school. Søs falls out with Peter, Mie is accused of theft, and his father is fired from his job and talks about selling the house. Everyone is looking forward to a sad Christmas, but maybe Lilleper will still go to the "Christmas Ball in Nisseland."
