Some of us take a large portion of our DNA from the father's side, other the mother's. With 28-year-old Thomas Seyr (Romain Duris), it's a 50/50 affair. He is just as much as (maybe even more so) of a thug as his father is in his shady activities as a real estate broker, but at the same time promising material for concert pianist following his mother's footsteps. His father, over-the-hill but refusing to quit, we see considerably in the movie. His mother we never see, as she died when he was a youth, shattering his musical dreams.
The plot is not so much of a linear story, but more of a cross-sectional cuts of various aspects of Thomas' life. On the more mundane side are his business activities that alway verge on being criminal, his affair with his partner's neglected wife and his relationship with his father to whom he seems quite devoted.
More interesting is his musical pursuits, triggered by a chance encounter with his late mother's manager who remembers his talent and invites him to an audition "when he is ready". This leads to his seeking help from an accomplished pianist Miao Lin, a young women who studied in the Beijing Conservatory, just arrived in Paris, speaking no French at all and "just a little" English. (Here we see the not unusual sloppiness when an Asian aspect is covered in a "western" movie. There is absolutely no logical reason for a woman from China to be speaking Vietnamese, except for one - the actress IS Vietnamese). Anyway, the communication purely through music and gesture is very well handled.
The shooting style is quite contemporary, and leans towards using darker scenes. Interesting to note that in the two series of piano practicing scenes, it's always dark and gloomy when he plays at home, but is reasonably bright when he is at coach Miao Lin's place.
As with such non-story-oriented movies, the ending is inconclusive. But that does not matter as it is the character study that is of prime interest.
