Like Voltaire's Candide in his eponymous novel, Jallel, a young North-African man, dreaming of better prospects, immigrates illegally to France. He struggles at first as he is unable to find work and finds it difficult to make friends. But soon he gets to sell fruits in the underground, albeit illegally. He also makes some new friends and then falls in love. But his dreams of success remain unrealized as he comes to discover and share the solidarity of the other outcasts going from one encounter to the other, making his way through Paris, from hostels to immigrant aid societies and social welfare groups, living among the excluded and the destitute.
