The game begins with Jutah Fate, a war criminal, being drafted into a covert military operation by his home planet of Hornet. Seven years prior, he was ordered to destroy an enemy stronghold, only to find that there are civilians inside. Due to the trauma of having to follow his orders, he is largely devoid of emotions. The mission is to destroy a space cruiser, known as the Dante, that is threatening the planet. Also part of the mission are Benoit Manderubrot, a political criminal; Micino Tifone, a spy; and John Loss, an escape artist and member of an oppressed tribe. The operation is headed by CO Annri Ohara. Upon arrival at the Dante, their ship is shot down by Dante's anti-aircraft weapons. Everyone lands on the cruiser unharmed, but Jutah is separated from the group. As the game progresses and Jutah is asked to destroy various parts of Dante, Jutah and Annri begin to develop feelings for each other. Finally, Jutah reaches Dante's bridge, but finds that the crew was killed by its own defenses. A hologram of Benoit appears and reveals that it was he who killed the crew, and that he had taken control of the ship and still planned to destroy Hornet. After Jutah refuses to join with Benoit, Benoit tries to kill Jutah by ejecting him into space. He is rescued by his crew as Benoit seals off Dante. Jutah breaks back into the ship and destroys Dante's powerful cannon in time to save Hornet. With the cannon gone, Jutah finds Benoit in the ship's core, and discovers that Benoit has bonded himself to the Dante's AI. After the final battle, Benoit activates Dante's self-destruct system. Jutah tries to get back to his ship, but his way is blocked, forcing the others to leave without him. The game ends with Jutah visiting Annri at her home three years later.
