Once upon a time a boy was brought up in a garage where everyone liked to sing. It was 1939, he was 8, and he liked puppets and operettes. Then he wanted to make films, but his father made him study mechanics. It is a film about Jacques Demy‘s youth, his games and pains, his first attempts to make films…This was a happy childhood, despite war and the post-war period. The story of Jacquot who had a vocation, was filmed by the woman who had been sharing his life since 1958.
