Naive, talkative Hoffi and mouthy Lehmi are as different as can be. But this doesn't dampen their friendship. When they wake up one morning in the middle of Dortmund Zoo instead of in their beds among the water buffaloes, it doesn't upset them, because the orderly lives of their fellow human beings aren't their thing anyway. What's much worse is that Hoffi has got it into his head to get a birthday present for his sister on this beautiful summer's day of all days, when you could actually be relaxing in the park with a crate of beer. The two lovable slobs embark on an odyssey through the city, at the end of which they lose sight of the present but have found their dream girls.

Fourteen-year-old Jeanne has lived in a farm commune since she was two years old. Her mother and father live in city communes and rarely visit. This is one of the commandments given by Otto, who rules the commune: children are to grow up without parents. Knowing nothing else, Jeanne enjoys her outdoor life, surrounded by lots of other children, until she falls in love with 16-year-old Jean and her childhood paradise begins to fall apart.
