While on the set of his latest film, actor Guillaume Canet and his co-star Camille give an interview. Camille, who plays his daughter, tells the reporter that she doesn’t think Guillaume is "rock'n'roll," or, in other words, he’s not sexy. Guillaume is stung. He turns to his girlfriend, Oscar-winning actress Marion Cotillard, for validation and comfort.
But Marion is distracted because she needs to practice her Quebec accent for Xavier Dolan's next film. Fearing that he has actually become nerdy, Guillaume decides to turn things around by rejuvenating his image. But the extreme solutions he comes up with wreak havoc on set.
