World ex. KoreaA woman has moved in across the road. She lives on the third floor, just like Lelio and his father and everyone can see into each other's apartment. This is how Lelio and Mama Mutch get to know each other. And lucky it is! Gunnar, Lelios father, is more often gone than at home, the fridge is empty and there is also no money. Gunnar spends more and more time with his friend Gerd (whom Lelio cannot stand at all) and leaves Lelio alone. What is going on? But not without reason Mama Mutch is a researcher. She researches the diatoms, but also finds out what is wrong with Gunnar. And as she is above all really clever, she has an idea how to help and to retransform Gunnar into the Daddy he was before.
