Sensuikan Cappellini-gou no Bouken

World War II was fought between the Axis powers, originally an alliance between Japan, Germany and Italy, and the Allies, a coalition with the United States and Great Britain as its principal members. In September 1943, the submarine Comandante Capellini was right in the middle of the Pacific Ocean, transporting goods bound for Japan. At the time of the submarine’s departure, Italy was allied with Japan. However, with the change in government that year, Italy takes sides with the Allies after it sets sail. The Italian crew members Abele (Peppe), Simone (Francesco Bellissimo), Angelo (Paolo) are unaware that their country has become an enemy of Japan during their voyage, and anticipate receiving a big welcome from Japan. However, when they finally arrive after a long journey, a Japanese navy lieutenant commander, Hayami Yohei (Ninomiya Kazunari), is waiting for them with a furious expression.
