Captain Casey Abbott commands an American submarine in the Pacific during World War II. When a perilous mission to retrieve a new Japanese mine for study goes awry, he's forced to abandon a likable combat diver. Abbott's orders to leave a man behind appear to be justified, but his second-in-command believes he had ulterior motives:

By mid-1945, Hitler is dead and the war has ended in Europe. Halfway around the world, however, the fighting is still going strong on a small island in the Pacific. Okinawa was the site of the last battle of the last great war of the 20th century, with a casualty rate in the tens of thousands. Through it all, military cameramen risked their lives to film the conflict, from brutal land combat to fierce kamikaze attacks at sea. See the footage they captured and experience this intense battle the way the soldiers saw it -- in color.

Follow General Douglas MacArthur and his men from their exile from the Philippines in early 1942, through the signing of the instrument of surrender on the USS Missouri on September 1, 1945. Preserved by the Academy Film Archive in 2013.

By spring of 1942, Japan controlled the western Pacific, the Philippines, and large parts of Indochina. America and her allies knew that final victory could only be achieved by unconditional surrender and that would involve occupation of the Japanese homeland. This is the story Operation Downfall, the plan to invade and occupy Japan that would dwarf the D-Day landings in Europe. According to the plan, on X-Day--November 1, 1945--General MacArthur would lead an invasion force onto the beaches of Kyushu, the southern most of the Japanese Islands. Y-Day would follow six months later when the largest beach landing in military history would take Tokyo. Politicians and military strategists knew that Japanese resistance would be ferocious. Plans for the invasion continued throughout 1945 until President Truman made the decision to drop the atom bomb. We trace the invasion plans from Pearl Harbor to Hiroshima and analyze why Truman chose the bomb over Operation Downfall.
