a very lonely, aging man,who sees his bright
future no more.For some reason he gave up his
life and his passion:music.He was a
composer.When he meets the boys for the first
time,it seems like he is going to lose the first
"battle“ for the authority in the classroom.He
gets involved in a few incidents with the boys in
presence of Rachin,but surprisingly for the
boys,Mathieu steps up to protect the boys
against punishments.The boys appreciate it and
start looking at Mathieu like a man who cares
about them.When a small group of boys led by
Pierre Morhanges teals Mathieu's briefcase with
music scripts,theprefect gets an idea.He
establishes a chorus.
