In The Early Morning Hours Of October 24, 1944, the legendary U.S. Navy submarine Tang was hit by one of its own faulty torpedoes. The survivors of the explosion struggled to stay alive one hundred and eighty feet beneath the surface, while the Japanese dropped deadly depth charges from above. With their air supply running out, some of the crew chose to make a daring ascent through the escape hatch. In the end, just nine of the original eighty-man crew survived. For those who did, it was the beginning a far greater ordeal.
