From the first scenes, you know the nature of service wished by Christelle from Pascal. And the performances of Anne Sophie Trebel and Bruno Henry, the wise use of contrast between them remains the important one.
A family father, proud by his son. His fragile young lady coworker. Her reserves to say what she wants from him. And, the direct confession.
The last minutes are easy to define as twist. But the emotional contain matters more , explaining, again, not so surprising, the gesture of Christelle , les crazy than it can be defined at the first sight.
A beautiful film. After its end, not the story itself remains in memory but especially its bitterness.
