L'Enfant du secret (1996)

Blanche, a social worker living in Southern France is assigned the case of a five year old deaf boy, who is found by a Gypsy lady after having been abandoned and tied to a shed near her trailer. The boy's life is in danger apparently because he is related to the family of a local politician who is seeking election as mayor. Blanche, though suffering from manic depression and thus emotionally vulnerable, decides to take charge of the situation, get her act together and besides being told to drop the case, seeks to discover the secret the boy has inside.
