Still feeling the effects of a tragic loss from the previous battle, Hikaru is assigned a new Valkyrie fighter. Global wants to test out a barrier defense system against a new attack by Quazmin. But for the Ontario region where the battle takes place, this could end in disaster. And in the female Zentradi fleet, Milia approaches her commander, Moruk Laplamiz, to gain permission to be micronized so she could infiltrate the Macross.

In a surprising turn of events, Exsedol Folmo is micronized and attempts to seek peace negotiations with the people of the Macross. During the negotiations, Exsedol reveals that the defection of the Zentradi soldiers could be related to a new cultural awakening caused by Minmay's songs. Hikaru begins to long for Misa, who is still on Earth, trying to convince her father and the UN that the two races may have a chance of co-existing peacefully.

Exsedol and Global gather the crew of the Macross to reveal the origin of the nomadic Zentradi at last. Meanwhile, Quamzin's forces attempt to steal a macronization chamber.
