Three Came Home (1950)

Agnes Keith (Claudette Colbert) and husband Harry (Patric Knowles) have lived in Borneo for years. Harry is a British officer, while Agnes has written a well-known book on the country. Their lives are disrupted when the Japanese invade in December 1941. With men sent to one prison camp, and women and children to another, the couple must survive apart despite cruel treatment by their captors. For three years, their physical stamina will be tested by malaria and sadistic prison wardens.
