Everything is normal with the Krumborg family – but when you know them, nothing can surprise you anymore. The two robbers Boris and Ivan want to kidnap Krumme. Krumme wants to learn to ride a horse. Mom wants a healthy Christmas. Dad doesn't want a healthy Christmas. And it's hardly surprising that Krumme's Christmas present for Yrsa ends up under Mrs. Olsen's bed, or that caretaker Svendsen tries to repair Mrs. Olsen's sink – even though it's not broken. And the youngest member of the family, Grunk, has eaten all the Christmas decorations. Yes, everything is completely normal in the Krumborg family...
The tween, Mads, finds it hard to fit in. Having feelings for a girl in class and a clumsy farther who is a teacher at his school doesn't help. By an unforeseen chance of events, Mads becomes somewhat of a hero, but will he win the girl?
