Tom Denison hears the story of 'Old Mary', who was found floating in a boat near Tahiti as a child in 1805. She lived a life of adventure and tragedy, experiencing piracy and the death of her children from smallpox, and witnessing the death of her beloved husband after his ship was captured by pirates. Eventually she settled on Tubuai Island, where Denison met her when she was approximately 70 years old.
