1960年的夏天，社会学家埃德加·莫兰和让·鲁什对巴黎年轻人的日常生活进行调查，了解他们对幸福的理解。这部论述电影连续几个月跟踪调查的进行，也记录了主人公们的变化。调查中被采访的人最后在影片第一次放映的时候聚集在一起观看进行讨论，有人的赞同，有的人驳斥。两位导演通过这部真实电影，经历了既极具挑战又充满乐趣的体验。
"In the summer of 1960, Jean Rouch and Edgar Morin investigated the everyday life of people living in Paris. ""Are you happy? How do you live?"" These are some of questions they asked young people on the street in an attempt to understand their idea of happiness.
From manual labourers, students, to a couple of office workers, the different protagonists reveal themselves in conversation, unconcerned about the presence of the camera. With no script, and no professional actors, this film sets out to frame the limits of cinematographic truth."
