The White Base heads for the debris field known as the Texas Zone. However, Captain M'Quve plots to take down the Gundam to win favor with his superior Kycilia Zabi. At the same time, Lalah is testing the new mobile armor Elmeth, with Char observing nearby. M'Quve sets numerous traps to lure the Gundam into the depths of the colony, but...

During the battle for Solomon, Mirai goes to see Sleggar while his damaged G-Fighter is being serviced. Understanding her tears, Sleggar entrusts her with a ring he says is a memento of his mother. And then their lips touch... Vice Admiral Dozle Zabi decides to abandon Solomon, and charges into the Federation's main fleet with the mobile armor Big Zam.

The Federation Forces finally begin their battle to capture Solomon. While the advance fleet holds its position, the main Tianem Fleet deploys mirrors in Side 1 airspace. As the mirrors gather the sunlight into a focal point, Solomon is burned by the intense ray. This is the power of the Federation Force's trump card, the Solar System. Aiming toward the newly opened breach in Solomon, the mobile suits begin their advance!

At a lakeside cottage, Amuro meets a mysterious girl staring at a swan. On his way back from bidding farewell to his father, the treacherous roads cause Amuro's vehicle to become stuck. His rescuer is none other than Char, who has recently arrived at Side 6. At his side is the girl from the lakeside, Lalah Sune. The White Base departs Side 6, and waiting for it is the Conscon Squadron!

The White Base enters the neutral territory of Side 6. Inspector Cameron Bloom, who was engaged to Mirai, finds his warm reception met with cool indifference. Meanwhile, Amuro finds his lost father Tem. But Amuro's father seems to have suffered brain damage due to oxygen deprivation, and Amuro weeps at the immense shock and sadness of the situation.

Captain Char asks his former subordinate Lieutenant Dren to intercept the White Base. Sleggar sorties in a G-Fighter, while a Rick Dom formation begins its attack. As Dren focuses on the fleet battle, he hears a report that the Gundam is missing and becomes uneasy. The Gundam approaches from directly overhead to avoid being spotted, and attacks the bridge of Dren's flagship!

In order to divert the enemy's attention away from the main fleet launching into space from Jaburo, the White Base is sent on a completely different course as a decoy. Meanwhile a new officer, Lieutenant JG Sleggar Law, has joined the crew. Char rushes to chase them into space with his Zanzibar mobile cruiser. Along the way he realizes the White Base is just a decoy, but decides this is a good opportunity to launch a pursuit attack...

Char has not given up on trying to find out more about the new mobile suits, and attempts to receive reinforcements from a Papua supply ship. But on the White Base, officer cadet Bright Noa decides this is a chance for a counterstrike, and sends out the Gundam and Core Fighter. With skill far beyond that of a novice, Amuro successfully guides the surprise attack.

With the formal admission of the White Base crew into the military, the question arises of what to do with Katz, Letz, and Kikka. After escaping from a childcare center, the kids run into a GM factory. Here they stumble into Zeon commandos who are planting bombs, and they are tied up. The children cut their bonds, and work hard to dismantle the time bombs, but...

The White Base arrives at Jaburo, the Earth Federation Forces headquarters in South America, but it has been followed by the enemy Mad Angler unit. Char joins the first wave of the attack as a huge formation of Zeon forces appears in the skies over Jaburo. Countless mobile suits descend, and a full-scale offensive begins. In the midst of battle, Amuro discovers Char's red Z'Gok!

The stowaway Miharu is discovered by Kai, who hides her in his own room. Immediately after he gives Miharu some information, Char's subordinate Flanagan Boone visits the ship and contacts Miharu. After watching the children on the White Base get caught up in the ensuing attack, Miharu feels guilty and goes out with Kai in the Gunperry, but...

Kai decides to leave the ship, and Miharu invites him back to her house. Realizing the situation of Miharu's family, Kai lets slip some information about the White Base. Miharu immediately relays the information to Char's Mad Angler unit, and Char orders her to infiltrate the White Base during a diversionary attack.

The White Base docks at the Belfast supply base for repairs. This information is passed by the female spy Miharu to none other than Captain Char, the Red Comet. Meanwhile, a Jukon submarine launches amphibious mobile suits called Goggs. The Goggs land and begin attacking the Federation ground forces. Amuro rises up against the Goggs, but the fight is close and difficult, and...

In the middle of testing out the G-Fighter, Amuro witnesses a Federation plane taking off from Zeon territory. Amuro follows it to the mobile command ship Big Tray, and informs General Elran of the existence of a spy. The traitor general shows his true colors when he draws his gun on Amuro, but Federation soldiers restrain and arrest him. Operation Odessa is now in effect!

Matilda's return to the White Base raises the crew's morale, and they take a commemorative photo. The Doms of the Black Tri-Stars, however, are approaching the White Base. Sayla is chosen to be the pilot of the G-Armor, and sorties with the Gundam despite feeling overwhelmed. But the three Doms perform their Jet Stream Attack and make sport of the Gundam!

Ensnared in M'Quve's trap, the White Base makes an emergency landing. While the worried Mirai anxiously waits for resupply, Bright formally designates her as substitute captain. Meanwhile, General Revil has just arrived at the European frontline base. Holding the White Base in high regard, he sends Matilda to repair its engines and deliver a Gundam support machine called the "G-Fighter," but...

Bright is unable to bear the strain of overwork, and collapses with a high fever. M'Quve's forces bomb the White Base's Minovsky particle generators and ECM transmitters, rendering it defenseless. Substituting for Bright is the rookie commander Mirai Yashima, whose lack of situational awareness and experience throw the battle into great disorder and confusion.

After Ral's death, Crowley Hamon intends to complete their mission so that she can repay his affections. With the remains of her limited military force, she begins a "drill maneuver" to break through the weak spot in the White Base's defenses. Amuro senses the incoming suicide bomb attack. As the Gundam tries to hold back the bomb, Hamon appears behind the Gundam and takes aim with her Magella Top's cannon!

The assault carrier White Base collects refugees rescued from the recent battle. Most of the regular military crew aboard the White Base have died or are seriously injured. The surviving youths aboard the ship are working together to escape from the colony. Meanwhile, Char seeks out the secrets of the Federation's mobile suits by personally infiltrating Side 7. A girl named Sayla Mass spots him, and Char is shocked at how much she resembles his sister...

After returning to the White Base, Amuro is held in isolation. Meanwhile, with his resupply delayed, Ral switches his strategy and uses small Cui tanks and hand-to-hand guerilla warfare. Ral and his men expect their enemy to be formidable, but when they find nothing but child soldiers aboard the White Base, they cannot hide their astonishment. Within the chaos, Ral runs into Sayla, but...
