SGM Jeanne leads her squad on unapproved recon maneuvers even though the army is on alert due to a recent attack on the Development Center on the moon, Alpha. Meanwhile, the Zor have arrived around Glorie and one of their city ships begins the decent into the atmosphere.

The Southern Cross Army manages to decode and decipher a number of transmissions from inside the large Zor ships. With the information learned, the Southern Cross High Command has decided to launch a pre-emptive strike against one of the Zor city ships.

SGM Jeanne volunteers herself and members of her squad to assist in a mission to try to break through the Zor blockade and contact Liberty for assistance in repelling the Zor forces. When the engines of Lt. Borg's shuttle refuse to shutoff, the shuttle plows into the energy barriers of one the Zor ships and attracts fire from the Zor forces.

Corporal Louis Ducasse figures out a plan to disable the drive system on the large Zor space ships. The 15th is dispatched to enact a plan.

The members of the 15th squad prepare to explore the downed Zor space ship to learn about their foe. Bowie does some soul searching and wonders whether if he wants to be a member of the military, when his real dream is to be a pianist.

The 15th squad is cut off from the Southern Cross command by the Zor commanders. They split up in an attempt to gather more information and to find a way back out. Bowie meets Musica, the decisive one of the musical triad. Meanwhile, the Zor fleet commanders contact Claude Leon and offer a peaceful settlement if the humans agree to become biohumans, like Seifriet.

Seifriet is taken in for questioning after being found by Lana, barely conscious on the battlefield. Major George Lombard arrives from the Liberty Patrol fleet to assist Glorie against the Zor. The Southern Cross High Command is disturbed when they realize this is the only help Supreme Commander Reinhardt has sent from Liberty.

General Emerson sees to it that Seifriet is taken to a doctor of his choosing so that this biohuman isn't destroyed like the last one. Efforts to restore his memory prove useless, so he is moved to a military hospital in attempts to remind him of his military background.
