25 year-old Hippo doesn't have a job, doesn't study either but lives from the money his younger brother earns with dealing and from occasional Poker winnings.

David, son of a bankrupt printer, lives in the Paris suburbs, as do Blacky and Nérone. If they are repeating their baccalaureate, they have forgotten to be stupid; and to make pocket money, they always find good tricks. One day, David meets a young student, coming from a very well-to-do background. He falls madly in love with her, and does not know how to seduce her.
