However, not everyone is supportive of Pierre's efforts. Moriette, who has a troubled past, is skeptical of Pierre's methods and worries that the choir will only lead to more disappointment. As tensions rise, Pierre faces resistance from some of the staff and students, who doubt the value of the choir.
Pierre, a former music conservatory student, is determined to make a difference. He discovers that the school's choir, once renowned for its excellence, has disbanded due to a bitter rivalry between the former music teacher and the stern headmaster, Michel Moriette (played by François Berléand). i--- Les Choristes Subtitles
