A long war between humans and machine men has resulted in peace, at least ostensibly.

Earth has ended a long war with an alien race of machine men, however both sides live under a stalemate-mutual truce situation. But a fuse is lit on this situation by the space pirate Captain Harlock, whose attacks on the machine men threaten to end the truce and reignite the war. Captain Warrius Zero has been appointed leader of a crew made of Earth and machine men, and is assigned the near-impossible task of capturing the legendary Harlock. However, as Zero goes about his mission, he is beset with malfunctions, mutinies, spies, and above all a secret truth that could change everything about the truce.—Q. Leo Rahman

The long war between the planet Earth and the machine men is finally over, resulting in a peace that is more a victory for the machine men than the Earth. Warrius Zero lost his family in the war to the machine men but despite this he is still is a member of the Earth fleet that is now working in concert with the machine men. His ship, made up of both humans and machine men, has been given a near impossible task: capture the space pirate Captain Harlock. While Zero struggles to accomplish this task, evidence begins to surface that the peace between machine men and Earth may not be as it seems.—ANN
