1960年的夏天，社會學(xué)家埃德加·莫蘭和讓·魯什對巴黎年輕人的日常生活進行調(diào)查，了解他們對幸福的理解。這部論述電影連續(xù)幾個月跟蹤調(diào)查的進行，也記錄了主人公們的變化。調(diào)查中被采訪的人最后在影片第一次放映的時候聚集在一起觀看進行討論，有人的贊同，有的人駁斥。兩位導(dǎo)演通過這部真實電影，經(jīng)歷了既極具挑戰(zhàn)又充滿樂趣的體驗。
　　"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."
