Joining the crew is Jeong-man, a former colleague of Hae-jun's father, assigned to Eclipse as captain. Though his job is to oversee the withdrawal of the ship, he suggests conducting some drilling one last time.
After 3 weeks of preparation, Hae-jun takes new recruit underwater, but he sinks to the bottom of the sea when his equipment fails. Shortly after, crew members begin to turn up, one by one, dead,. What the few survivors soon discover is a transparent underwater creature they encountered once before.
