Rosa, the belle of Little Italy, is beloved by Luigi, a bootblack. But her heart is with Antonio, in Italy, to whom she sends enough money to bring him to America. When Antonio comes, instead of being faithful to Rosa, he spends most of his time in the wine shops of the quarter. One day Rosa finds him flirting with another girl. This so angers her that she turns on him and refuses to have anything more to do with him. He comes to explain, but she will not relent. Seeing Luigi’s faithfulness, she accepts him. They are married and live happily for a time. Then one day, Rosa loses a locket bearing her picture, and Antonio finds it. In a wine shop he shows it to Luigi, claiming Rosa gave it to him. There is a quarrel and arrangements are made for a duel. Rosa hears of this, and, with her father and a policeman, arrives in time to prevent the fight. As Luigi turns to Rosa, Antonio makes a lunge at him, but Rosa throws herself in front of her husband, receiving the knife thrust into her arm, Antonio is taken into custody and Luigi attends to his wife, who isn’t so very badly hurt. Her explanation about the locket wipes out the faintest suspicion from his heart and all is peace again.
