Sacha (Gad Elmaleh) is a talented jazz pianist who does not take life too seriously. He loves his friends, his piano, and he loves to party. At night, he plays in a jazz club and enjoys seducing pretty young girls. He lives for the moment, looking for pleasure, with no responsibility, no family, and no taxes. Sacha's carefree life changes suddenly when he meets a forty-something career woman named Charlotte (Sophie Marceau) one rainy afternoon. After they make love, Sacha discovers that Charlotte has three children, not to mention a jealous soon-to-be ex-husband who runs the multinational company they both work for. Although she no longer loves her husband, she has a hard time untying the knot because of his wealth and power. Sacha and Charlotte have seemingly nothing in common, but they may just be made for each other.
