París-Tombuctú.

The frustration and vital weariness of Michel des Assantes, a prestigious plastic surgeon in Paris, is unbearable: he has a wife whom he does not love, a son who is foreign to him and friends whom he despises but, at the same time, he is incapable of taking his own life. One day, he buys a bike from a bizarre cyclist who was to make the Paris-Timbuktu route and sets out to make the journey: then, Timbuktu becomes for him the Promised Land.
