Lotta Petermann is looking forward to her first class trip. Finally without parents and with her best friends Amrum unsicher machen - that promises pure adventure! But Mama Sabine sabotages Lotta's plans and suggests Papa Rainer, of all people, to accompany her on the class trip - how embarrassing!

Motte is 15 years old in the fall of 1977 and has to come to terms with the news that his best friend Bogi has to go to the hospital with a life-threatening illness. This is a seemingly impossible task, because his first love, his parents' impending divorce, his enthusiasm for Bowie and soccer, an omnipresent chimney sweep, and his anger at not being able to share all this with Bogi overwhelm Motte and lead him to make himself scarce at the hospital.
