In the whirlwind life of Guillaume Canet, playing a heightened version of himself, success as a director and a happy home with his partner, the famous actress Marion Cotillard, seems assured. Yet, a creeping sense of domesticity and a nagging fear that his rock 'n' roll spirit is fading prompt a drastic, midlife decision. He embarks on a quest to reclaim his youthful edge, dragging his bewildered friends—including Gilles Lellouche and Yvan Attal—into a series of hilariously misguided adventures that strain his relationships and career. Directed by Guillaume Canet, this meta-comedy blends music and farce as it explores the chaotic pursuit of lost youth, featuring a stellar French cast including Fanny Ardant and the legendary Johnny Hallyday. The film vibrates with the energy of its soundtrack, asking whether one can ever truly go back to the wild days, or if the greatest rebellion is embracing the life you've built.
