Le bonheur c'est une chanson triste

Imagine it is summer and that, for the last several days, Montreal has been swimming in sweltering heat and smog. Then imagine that you are in the city's downtown core and a woman holding a small video camera approaches you. She asks you to participate in a one-question survey. Although you are slightly wary of this proposal, you stop to listen. She asks you: "What does happiness mean to you?" and awaits your answer. (imdb)
