本片基于真實(shí)歷史故事改編。1942年1月，日本戰(zhàn)爭機(jī)器的鐵蹄席卷東南亞。在這里，有一個叫做新不列顛的島嶼上，有一座天主教傳教站，這里的澳大利亞護(hù)士們克服種種困難的條件，悉心照顧手上的澳大利亞士兵。(文/life_is_good@YDY)
　　January, 1942. The Japanese war machine thunders across South East Asia. In its path,on the island of New Britain, lies a tiny Catholic mission station, Vunapope. Here a handful of Australian nurses take refuge with wounded Australian soldiers.
　　Sisters of War is inspired by the true story of two extraordinary Australian 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. Although 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.
