This offbeat musical drama concerns Lucas (Bénabar), an up-and-coming singer who spends 10 years from the 1990s through the 2000s working his way up to the top of the French pop scene. Unfortunately, he only manages to do so by stealing the tunes of his songwriter friend Thomas, who has vanished into thin air. When Thomas suddenly reappears at the height of Lucas's success, then, it threatens to bring everything that Lucas has worked so hard to build violently crashing down.
