During the annual party in the château of a wealthy French family, a murder is committed. The small neighboring town is thrown into disorder, suddenly plunged back into the old relationship of master and serfs.
Raised to believe in performance and in the idea that all abilities must be optimized, Emma is a young, methodical woman who appears determined and relatively sure of herself. But two consecutive failures (real or imagined) lead her to believe that she has a real problem: she is useless in bed. Because she is more fragile than she appears, Emma hence decides to become... the best lay in Paris! She then sets out on a formidable plan of action (theory, practical, validation of acquired knowledge), which soon provokes a series of misunderstandings and disasters within her immediate vicinity. For one thing, her method doesn't turn out to be really adapted to her field of investigation. And Emma has probably also forgotten a little detail: love doesn't obey any plan. In this absurd and nutty quest, Emma will learn to let go, to lose control, and, to finally win her freedom.
Armelle, a French nurse who just recovered from the stab in the face she got from Nadim, his partner, starts a search to get back her daughter, who was taken away by Nadim. Alone before the law, she will do all she can to reach her objective. She puts up posters, founds an association, gets funds to pay for the search, and informs the media about it. An amazing human team gets down to work from France to Montreal, including Paris and Vancouver, until Armelle can hug her daughter again in an airport in the east of Canada, almost three years after she had lost her.
