In the summer of 1945, US troops stood off the coast of Okinawa. The battle between Japan and the USA entered its final, decisive phase. A Japanese submarine and a US escort destroyer engaged in a cat-and-mouse game both above and below the water. In addition to the feature film, the DVD box set includes seven documentaries about the Battle of Okinawa: Duel in the Pacific, The Battle of Saipan, Kamikaze: The Divine Wind, War of the Submarines in the Pacific, War in the Pacific, D-Day, and The Island Battle of Tarawa.
