A young man named Antoine refuses to do his military service. When an officer comes to get him at his mother’s house, Antoine tells him that he won’t go, that he can shoot him for all he cares. He has just turned twenty. It’s 1968 and, like the rest of his generation, he’s got nothing to lose. Hundreds of thousands of youngsters like him run through the streets, hoping to end the boredom of a programmed life. During a riot, Antoine will encounter both a young lady, and love. They will live together with a group of people in an apartment.
