At a French boarding school for troubled youth in the early 1970's, the Headmaster and his wife decide that their son Daniel, who is fifteen years old but looks younger, should finally go live in the dorm with all the other students, as they do not want it to seem Daniel is receiving any special treatment. Daniel is now faced with the challenge of earning the trust and respect of the other students, who all come from troubled backgrounds.
