By 1838, in Port Arthur, Mrs. Vickers has died. Sylvia has lost all her memories of the incident at Macquarie Harbour and knows only what she has been told about it. She is now a young woman of sixteen and engaged to Captain Maurice Frere, who has told the story of the mutiny in his own way: making himself the hero and claiming that Dawes attempted to murder all three of them. News arrives that the surviving mutineers of the "Osprey" have been captured and are to be tried at Port Arthur. Sarah Purfoy calls on Frere and begs him to speak in Rex's favour, saying that he left them food and tools. She threatens to expose Frere's previous affairs to Sylvia. Frere consents to her demands. Rufus Dawes is also brought down from Hobart to identify the captured men. At the trial, he sees Sylvia again and realises that she is alive: he had been informed of her death. He tries to speak his case but is not allowed to. The mutineers get away with life sentences.
