Maria Nikolai was once a celebrated musician. 20 years ago she came to Hamburg with her husband, who has since died. But her neighborhood, which used to be a neighborly neighborhood, is gradually threatening to turn into a social hotspot: the streets are dirty, young people are killing time in front of the supermarket and alcohol is a constant companion for many. Foreigners have also been increasingly moving to the district for some time.

Isi and Ossi couldn't be any more different: She's a billionaire's daughter from Heidelberg, he's a struggling boxer from the nearby town of Mannheim. But when Isi meets Ossi, the two quickly realize that they can take advantage of one another: She dates the broke boxer to provoke her parents and get them to fund a long-desired chef training in New York. He tries to rip off the rich daughter to finance his first professional boxing match. Their plans soon develop into emotional chaos that challenges everything the two believe to know about money, career and love.
