Muriel is a beautician. She's talkative, a bit of a liar. She likes telling fanciful tales. For twenty years, Muriel has also been the number one fan of a successful pop singer, Vincent Lacroix. His songs and concerts almost fill her entire life. When Vincent, her idol, knocks on Muriel's door one night, her life is turned upside down. She is dragged into a tale that she never would have dared invent.
