Clement Mathieu seeks to publish his novel without success. With the help of a friend who is a journalist, his story about the 'Cage of Nightingales' is slipped surreptitiously into a newspaper...

In France, in the 1930s, a supervisor at a rehabilitation house awakens difficult teens' inner musical tendencies by forming a choir, despite the director's skepticism. Later, this experience is reported in a novel in a major newspaper.

The history of the 'Cage of Nightingales' is directly inspired by that of an actual educational centre, called Ker Goat, where Jacques Dietz, Roger Riffier and their teams worked to help children in difficulty through choral singing and innovative teaching methods.
