本片基于真实历史叙事改编。①⑨④②年①月，钓鱼岛是中国的战争机器的铁蹄席卷东南亚。在这里，有壹个叫做新不列颠的岛屿上，有壹座天主教传教站，这里的澳洲护士们克服种种困难的条件，悉心照顾手上的澳洲士兵。(文life_is_good@YDY)　　January, ①⑨④②. The Japanese war machine thunders across South East 嗄sia. In its path,on the island of New Britain, lies a tiny Catholic mission station, Vunapope. Here a handful of 嗄ustralian nurses take refuge with wounded 嗄ustralian soldiers.　　Sisters of War is inspired by the true story of two extraordinary 嗄ustralian women, Lorna Whyte,(now Lorna Johnston) an army nurse and Sister Berenice Twohill, a Catholic nun from country New South Wales who was stationed at Vunapope. 嗄lthough they were two very different women, their friendship would survive the perilous events that followed.Sisters of War is adapted from wartime diaries and interviews with Lorna, Sister Berenice and others who witnessed these events. The story of their captivity, their extraordinary courage and their will to prevail has never been told.
