Uncover the amazing story of the ill-fated Australian Gallipoli Campaign in Turkey that has been overlooked for almost a hundred years. This is the incredible true story of the submarine AE2 and her crew. Experience their terrifying dive into enemy territory and ride along on a modern-day scientific expedition to see if the submarine can be saved. The story begins in the early hours of April 25, 1915. Lt Commander Henry Stoker and the crew of AE2 are ordered to break through the heavily defended Dardanelles Strait, disrupt Turkish supply lines in the Sea of Marmara and generally run amok. It's a mission many consider impossible. During the previous month, an Allied fleet tried to penetrate the Dardanelles, suffering heavy losses. Three ships were sunk and more than 600 men killed. Two other submarines made attempts on the strait but failed. AE2's exploits would become the stuff of submarine legend. But after the horrors of the Western Front and the Gallipoli campaign, her story was largely forgotten... until now.
