Charismatic and resourceful, seducer and daredevil, Jean-Paul Belmondo has always played his roles as he lived, at a thousand miles an hour. He had only one passion: to entertain the public with his smile, his naturalness, his energy, his stunts. But contrary to appearances, his destiny was full of pitfalls. This film lifts the veil on a founding childhood that allowed him to overcome many obstacles throughout his life thanks to the tutelary figures of his father and mother. Told from the inside with the help of his autobiography, interviews and unpublished archives, this epic story traces the career of this turbulent young actor who launched the New Wave in Breathless before becoming the popular Bebel, an indestructible and provocative vigilante. From film to film, this documentary paints an intimate portrait of a man who built himself up to reach the top: his triumphs but also his trials, his doubts, his secrets, his angers, his clowning, his disappointments or his personal dramas.
