A married woman grows closer to a seemingly dangerous man. Claire Gautier is an insurance adjuster who is in love with life, her husband and her five-year-old child. She is rational, composed and in control. She meets veterinarian Laurent Kessler when he files a claim with her company. Awkwardly and tentatively, his interest in her blooms, and before long he’s looking for excuses to knock on her door. While all stays above board, the conversations between them soon take on a special meaning and resonance, and it becomes obvious that they share a mutual understanding. However, there is a killer loose in the city and Claire has to ask herself whether her new friend is the "Doctor Death" for whom the police are hunting.
