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."
