A man tries to hold on to his bachelor lifestyle by getting engaged in this romantic comedy. Luis (Alain Chabat) is a man in his mid-fourties who has been happily unmarried all his life. Luis nearly wed his sweetheart when he was 21, but the meddling of his mother (Bernadette Lafont) and five sisters drove the young lady away, and since then he's devoted his romantic attentions to short-term relationships while earning a good living working in the perfume industry. However, his family remains determined to fix him up with eligible women, and Luis has grown tired of it. With the help of a colleague, Luis concocts a plan -- his friend's daughter Emma (Charlotte Gainsbourg) agrees to pose as his fiancée and then abandon him at the altar, which should silence his mother and sisters on the subject of matrimony once and for all. While Luis and Emma's relationship is all business, she does a flawless job of convincing his family that she loves him and is determined to be his wife -- so much so that Luis wonders if she might be serious about him after all. Directed by Eric Lartigau, Prête-Moi Ta Main (aka I Do) was a major box-office success in France, attracting nearly three million viewers in its first month of release.
