Charlotte Lewes, a young Briton newly widowed by the Great War, departs for colonial Burma in 1917 to escape the ruins of her life. As a schoolteacher in Rangoon she is rejuvenated by the sensuous Oriental climate, and she meets John Dollar, a sailor who becomes her passionate love and whose ill-fated destiny inextricably binds her to him. On a festive seafaring expedition, the tightly knit British community confronts disaster in the shape of an earthquake and ensuing tidal wave. Swept overboard, Charlotte, John Dollar, and eight young girls who are Charlotte's pupils awake on a remote island beach. As they struggle to stay alive, their dependence on John overwhelms him, and an atmosphere of menace and doom builds, culminating in shocking and riveting scenes of both death and survival.
