Louberger, director of an orphanage, is full of praise for a former boarder, Mr. Sauval, who has become their benefactor. One night he arrives and he does not seem to be exactly the man described by Louberger. He has in fact become a crooked lawyer and he is wanted for a crime he has just committed. Despite his efforts he will not escape the police but he will manage to remain, in the eyes of the children, at the height of his legend.

In France, in 1930, a supervisor of a boarding school for young offenders seeks to awaken the music by forming a choir, despite the skepticism of his boarding school director.
