At Håkan Andersson's house, life is not quite as it usually is, because mother is not at home, she is admitted to Malte Severin's stress clinic. And father Rudolf, who is the world's most clumsy father, has to manage the family by himself.
Even thieves don't dare steal from superheroes, so Håkan's laser weapon is almost the only thing left in the house. No furniture left and the kids get chips for dinner; maybe after all Rudolf has to tell Karin that she is needed at home.
Malte Severin gives the family a restraining order against Karin, who needs peace and quiet. The whole family goes to a garage sale and buys back their own furniture, which is sold by a "good faith" scammer.
Håkan's turn has come to bring the whole class home for a visit, but unfortunately he has forgotten to tell dad. So now you have to be incredibly smart.
It's toy day at school and Håkan brings Robot Rex, cleverly disguised as Santa. But Rex ends up in a forced marriage with a wedding barbie, the disaster is a fact.
Håkan is no longer allowed to play with Ronny and instead plays with strong Alice. In addition, Håkan gets extra help with writing letters from extra Miss Veronika.
Rudolf gets to attend a parent-teacher conference at school, Håkan is misunderstood at school but then meets the leader of the universe in his own high person.
Rudolf has no money and there are only ten days left until Christmas. Maybe all the Christmas presents can be bought at the midnight sale in the home textile store?
