He tries and tries to lose his virginity but his mother and older brothers never leave him alone. Even though an older priest makes a pass at him, Laurent's sex life is grim until he makes out with some girls at a party thrown by his older brother. But while his attempts to lose his virginity aren't going well, he acts out on other ways by smoking cigars, participating in a bit of petty theft and lying to his family at every occasion. He's having fun, but not the kind he's looking for the most.
It all seems to be for naught until he develops a heart murmur and he is taken by his mother to a very prim spa. While the spa might be refined and upper-class, some of them women take an interest in Laurent. And it isn't long before at least some of his dreams are coming true.
Murmur of the Heart won Louie Malle as Academy Award in 1973 for Best Writing, Story and Screenplay Based on Factual Material or Material Not Previously Published or Produced.
