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.
