Two very different girls, Blanche and Lea, become friends. The former is shy and reserved, while the latter is casual and brilliant. Léa is engaged to a young man, Fabien, who in character resembles Blanche. It is with her that he ends up in fact, during a long holiday of Lea, that however soon consoles with a young fatuous and charming as she, which was in love with Blanche before knowing Fabien.
