Raising money for the salon is proving to be difficult and, encouraged by her mother, Sandrine signs up for the Miss Montigny contest in the hope of winning and using the prize money to realise her dream. At the sign up Sandrine and her friend Gianna fill in the forms, guessing their vital statistics. This short-cut ends up being a big mistake.
The prospective Miss Montigny candidates are required to undergo training: comportment, singing etc., their tutor being a bit of a demanding woman. At a certain point their measurements are checked, and Sandrine is told that she is not eligible to continue as her bust measurement is too small.
Sandrine and her mother have some savings towards the beauty salon, and Sandrine decides to use some of the money to resolve the inadequacy of her breasts. This gets her back in the competition and as we watch her perform her song in the final, we all feel that surely she has won. And then they announce the first three places in reverse order, in time honoured fashion. She seems happy and confident, but the reason for her demeanour isn't quite what you would expect.
