Lettre à la prison 56 years old

In 1970, Tahar, a young Tunisian, travels to France for the first time to help his older brother, who is wrongly accused of murder and incarcerated in Paris. He first stops in Marseille, where he meets Tunisians very different from those familiar to him; enigmatic French people; and a strange atmosphere that makes him doubt his brother’s innocence, his own innocence and his own mental integrity.
