This film takes us back to July 30, 1945 when a Japanese submarine I-58 torpedoed the USS Indianapolis in the Philippine Sea. After four days at sea, 317 out of the 900 alleged survivors were rescued from the shark infested waters. According to the Discovery Channel, it is the worst shark attack in history.
But according to the men who survived the ordeal, most of the crew died from either exhaustion, exposure to the elements, or drinking the ocean water, not from shark attacks. Despite the claims of crew, the incident is described as one of the worst shark attacks ever.
