Gennarino is a Neapolitan orphan boy. He lives with Angela, his adoptive mother, a former famous singer now fallen on hard times. She has a serious illness, and they together try to get the money, necessary for her right care, by singing around. But one day Angela is obliged by the illness to stop her activity, and Gennarino decides to join a pilferers gang.

Robert and his fiancée Lucienne were due to go on vacation together to a tented village in Sicily. Robert is forced to postpone his trip and only joins Lucienne a few days later, taking advantage of the departure of a following group. During the train journey, he befriends Thérèse, a young Sicilian living in Paris, who wants to make a pilgrimage to the land of her ancestors. Lucienne is away from the camp when Robert arrives, so he can continue to see Thérèse, and little by little they discover that they love each other. When Lucienne returns, an explanation and reconciliation take place, then Robert changes his mind and, with the vacations over, leaves Lucienne alone to live in Sicily with Thérèse, who wants to stay in her family's homeland.
