Barcelona in the 1930's: with extreme makeup and outlandish clothes, "La Moños" (Julieta Serrano) is a mysterious character of Las Ramblas. Pepi, a girl of nine years, is fascinated by this extraordinary woman. Using her imagination, and collecting the stories she has heard, passionate Pepi reconstructs the life of "La Moños".
