Amelia, a beautiful and irrepressible girl known as "La Rossa", returns from Paris to her country, a small seaside town in southern Italy, where her father is the lighthouse keeper. To her father and her fellow villagers, she gives the impression that she is married to a rich gentleman. In reality she is only the friend of Pierre Dupont, an elegant Parisian bandit. Dupont, however, actually gives the girl a certain economic comfort. Later Pierre arrives in the country incognito, being wanted for a large theft of jewels in Paris, and Amelia, her lover and accomplice, helps him to hide.
