To be closer to his children following his divorce, Laurent Monier, a history and geography teacher in a peaceful provincial high school, accepts a position in a sensitive college in the Paris suburbs. He is assigned the hardest class, the fourth techno, and he finds an apartment in the Cité des Muriers, a particularly difficult district.

A provocative, seemingly absurd patchwork movie which sends a worthwhile message about hope against all odds, love, children and human understanding. Schoolgirl Victorine has an insane mother and an alcoholic father who can never find his way home in their maze of slum apartment blocks. Aggressive, sexually threatening boys of all ages are everywhere, and while the teacher eventually relents to a gang of adolescent rapists, Victorine gives herself to a rowdy gang of older layabouts, eventually winning the heart of burglar Paul.

Samba (Bakary Sangare) has returned unannounced to his home village, bringing with him a suitcase full of money. Despite his protests that this is money that he earned in the city, the villagers have their doubts. In fact, he held up a gas station and unintentionally killed its attendant, and is in hiding here. Meanwhile, he has married a woman (Mariam Kaba) with a child who left her husband and built a house for her. He is building a bar with his remaining money, but he encounters a situation which makes him believe that he will be exposed to the police, and runs away, leaving a pregnant, very ill wife behind, much to the disgust of the villagers and Samba's own family.

A Film by Jean Rouch and Tam-Sir Doueb.
