Pierfrancesco Favino (“The Traitor,” “Nostalgia”) stars as the chief officer of the ship which the two kids, named Carmine and Celestina, manage to board surreptitiously in the port of Naples, becoming clandestine passengers. The youngsters are on a mission to reach the U.S. where they dream of living with Celestina’s sister, who emigrated to New York two years earlier.
