Gilles and Christine are teenagers from unstable homes. When they do some shop-lifting together she is arrested, but he gets away. She escapes from a mental institution and meets him at an abandoned house in the country, where a large group of rebellious teenagers are having a wild, all-night party. American rock music from the period is played prominently and has a very strong effect, especially "Me and Bobby McGee," sung by Janis Joplin. Drugs are used, mainly pot and hash. As the party is winding down, Gilles and Christine escape even deeper into the countryside, searching for a commune where artists are said to live without electricity or running water. This is Christine's idea, but Gilles reluctantly goes along. A jolting conclusion shows us that, as Assayas puts it, "Gilles' real life has now begun."
