In a small town on the outskirts of Paris lives Lydia, a beautiful, dreamy girl. After being chosen to star in the end-of-year play inspired by Marivaux’s ‘The Game of Chance and Love’, she decides to buy a beautiful 18th-century princess dress for the occasion. Lydia knows it is a stage costume but cannot resist the temptation: she puts it on and struts through the streets of her neighbourhood with the ease of a true diva. Instead of thinking she’s mad, people are enchanted by her, as is Krimo, the local tough guy who falls for her at first sight. On the one hand, the boy would like to confess his feelings; on the other, he wants to maintain the tough-guy reputation he has among his friends. In the end, he decides to accept a part in the show and, thanks to his character’s lines, he finally manages to express his love to her.
