Le Grand voyage

The youngest son of a family of Moroccan immigrants who've settled in Aix-en-Provence, France, Reda tries to avoid all contact with his authoritarian father, a devout Muslim. However, one day he finds himself obliged to drive his father to Saudi Arabia to visit Mecca. During the trip, the two lock horns as the father refuses to speak French with him, and throws Reda's cell phone out of the car as he's speaking to his French girlfriend.
