Hitler's last secret weapon

25-year-old Elaine was active in the resistance movement against the Nazis and was ordered to spy on the German naval officer Hans. He would become the first mate of the submarine U864 and was assigned a secret mission. To Elaine's expectation, she fell in love with Hans. Even though Hans was engaged to another woman, he was deeply attracted to Elaine. At the critical juncture, Elaine successfully sent crucial information—the exact route of submarine U864 to Japan. The British suspected that Hitler planned to send mysterious weapons to weak Japan. U864 left port. For Germany, the trend of the war was getting worse and worse, so the atmosphere on the ship became serious.
