1968 and 1969 in Paris during and after the student and trade-union revolt. 20-year-old François is a poet dodging military service. He takes to the barricades, but won't throw a Molotov cocktail at the police. He smokes opium and talks about revolution with his friend Antoine, who has an inheritance and a flat where François can stay. François meets Lilie, a sculptor who works at a foundry to support herself, and they fall in love. A year passes; François continues to write, talk, smoke, and be with Lilie. Opportunities come to Lilie: what will she and François do?
