Plagued by attacks from a race of sea mutants dedicated to eradicating humanity, the crew of the Blue Submarine No. 6 fight for the fate of all mankind.
After surviving another undersea battle with Zorndyke's forces, the crew of Blue Submarine No. 6 returns to base for repairs; Tetsu continues to display his lack of concern for authority.
Tetsu drifts in the open sea and his life flashes before him before he passes out, but he finds himself rescued by one of the enemies.
The poles are shifting and most of the Earth's land is now under water.
