Output: Angela Chiaromonte Lillian Gish and Captain Giovanni Severini Ronald Colman are deeply in love, but Angelas wealthy father, Prince Chiaromonte, does not know this and arranges her marriage, without her knowledge, to the son of Count del Ferice. However, the prince dies in an accident. While Angela grieves, her older halfsister, the Marchesa di Mola, looks through their late fathers papers and secretly burns one of them. No will can be found, so not only does the entire estate go to the Marchesa, but because the princes second marriage was not registered with the civil authorities, it is not legally valid, making Angela nobody. With that, Count del Ferice dissolves the marriage contract between Angela and his son. The Marchesa orders Angela to leave the palace that very day, revealing that she has always hated her stepsister for whining her way into their fathers affection and for taking Giovanni, the only man she ever loved. Madame Bernard, Angelas companion and chaperone, takes her in. Giovanni finds her, but has some bad news. He has been appointed to command an expedition to Africa and must leave the next morning. However, he promises they will be married the day he returns. His camp is attacked by Arabs, and Italian newspapers announce that all have been massacred. When Angela hears the news, she becomes catatonic. She is taken to the Santa Giovanna dAza hospital, which is run by nuns. After several days, the painter Durand, himself hopelessly in love with Angela, paints a portrait of Giovanni and brings it to the hospital, hoping it will help. Angela at first mistakes it for Giovanni, kissing it several times, but then comes to her senses. After a while, she informs Monsignor Seracinesca, an old family friend, that she intends to become a nun, a white sister, in honor of Giovanni. However, Giovanni is still alive. For two years, he languishes as a captive until the death of his sole comrade gives him the chance to overpower their guard and escape. On the ship back to Italy, he is ordered not to speak to anyone until he has seen the Minister of War. That same day, Angela takes her final vows in a solemn ceremony, dedicating her life to the Catholic Church. Giovannis older brother, Professor Ugo Severi, breaks down after years of research trying to harness the power of Mount Vesuvius and is taken to the Santa Giovanna dAza hospital. Giovanni visits him, and by chance, meets Angela. After their initial shock, he embraces and tries to kiss her. She responds at first, but then remembers her circumstances and runs to her room. Monsignor Saracinesca restrains Giovanni from following, explaining that Angela is now married to the Church. Giovanni refuses to accept that. He lures Angela by false pretenses to his brothers observatory. He tries to get her to sign a petition to the Pope requesting a release from her vows, but she refuses. When Giovanni sees that all his pleadings are useless, he allows her to leave. The Marchesa tries to persuade Monsignor Saracinesca that Angela has gone willingly to be with her lover. He does not believe her, but sets out for the observatory anyway. Meanwhile, Giovanni notices that his brothers invention indicates that Vesuvius is about to erupt. He rides to warn the townsfolk, passing Saracinesca on the way. The Marchesas carriage is wrecked when her horses bolt, startled by lightning. Fatally injured, she crawls and stumbles to an empty church, her only thought to confess her sins before dying. By chance, Angela seeks shelter there. Not recognizing her, the Marchesa confesses she burned the will out of hatred and asks if her sister will forgive her. After a visible struggle with her emotions, Angela says she does, before her sister passes away. Vesuvius erupts, spewing lava and breaking a water reservoir. However, Giovanni has been in time. Most of the townspeople are saved. Giovanni though drowns helping a mother and her children. Afterward, Angela asks God to keep him safe until they can be reunited.
