A series of raids on commerce vessels prompts the Earth Homeworlds' General Assembly to send the entire Exofleet to wipe out the pirates once and for all.

Getting hammered by the pirate base's defenses, the Exofleet sends down Able Squad to take them out. The Martian finance minister discovers someone has been taking massive funds from the Neo-Sapian treasury.

The Exofleet races back from to Earth from Saturn, hoping to return in time to stop the Neo-Sapien attack. Marsh gets charged with mutiny when he disagrees with Captain Marcus' decision to split the fleet, sending the fastest ships ahead of the rest. Napier escapes from a work camp and tries to organize a small resistance cell.

Able Squad is stranded on Earth after distracting the Neo fleet, to allow the Exo-carriers to retreat. They make contact Napier's resistance, but get a cold greeting, as the Earthers blame them for leaving the planet unprotected.

Marsala takes control of the space tug and saves the container, crash landing on Venus instead. Nara goes off on her own to locate her family, while the others try to locate her thinking she was shot down.

Able Squad escapes from the brood chamber with Phaeton as a hostage (a useless one, since Typhonus wouldn't mind him dead). Once outside Phaeton tries to resist and is shot, he then falls down the mountainside. Able Squad climbs up the mountain so they can destroy the brood chamber. They then realize they can accomplish this by flooding it with magma. Phaeton returns to try to stop them, but J.T. defeats him in an e-frame battle. The mountain then explodes, and Weston and Takagi arrive just in time to pick up their fellow squad members. The episode ends with a preview for next season with Marsh and Typhonus each receiving missions from their leaders.
