PHANTOM OF THE SUBMARINE

Elite naval officer, Chan-suk, is arrested and executed for killing his senior officer. But he is only dead on paper, because Chan-suk finds himself assigned to a secret mission on board Phantom, the nuclear submarine. The submarine was given in lieu of a loan from Russia. All the crew members are legally dead and they refer to one another by numbers. The captain is killed by his deputy, 202, who orders a torpedo attack on a Japanese submarine off the coast of Japan.
