Lullaby

When Myriam decides to return to work, she and her husband look for a nanny for their two young children. They find their dream candidate: Louise, a quiet, polite and devoted woman who sings to their children, cleans the family's chic Paris apartment, stays late without complaint and hosts enviable birthday parties. But as the couple and their nanny become increasingly dependent on each other, jealousy, resentment and suspicions start to breed, and Myriam and Paul's idyllic domesticity is shattered.
