Uma cineasta vai passar férias em uma propriedade em Côte d'Azur com familiares e amigos. Apesar da linda paisagem, ela precisa lidar com um término recente e com os desafios de seu novo filme, enquanto o isolamento das pessoas ao seu redor as leva a externalizar uma série de sentimentos até então reprimidos.
The image of a mysterious, solitary filmmaker - a cineaste maudit - who flees from both the media and the public, is unrelentingly bound to the figure of Leos Carax, in France. Elsewhere, the real focus is on his films and he is considered to be an icon of world cinema. Mr.X dives into the poetic and visionary world of an artist who was already a cult figure from his very first film. Punctuated by interviews and unseen footage, this documentary is most of all a fine-tuned exploration of the poetic and visionary world of Leos Carax, alias "Mr.X".
Alice, fired from her job on an assembly line, leaves her boyfriend and provincial home for an uncertain new life in Lyon. There she encounters Bruno, a construction worker who's just been dumped and is severely depressed. Romantic possibilities ensue.
