The extraordinary true story of courage under fire and survival during one of the deadliest wartime attacks on Australia - the sinking of the hospital ship, the Centaur - and the bravery of its heroes. Ellen Savage, a fearless nurse from country New South Wales, emerged from a whirlpool of fire and burning wreckage, her body bruised and broken, and the only woman to survive. But for more than 34 hours, she and other heroes fought off hungry sharks, and did all they could to save other badly injured survivors until rescuers arrived.
