Reccoa and Kai attempt to escape their prison cell. Quattro is suspicious of Jaburo's light defenses, and Apolly learns that a nuclear bomb is planted on the base. With no possible way to defuse the bomb, everyone scrambles to escape the base before it detonates.

Karaba member Hayato Kobayashi pilots the airship Audhumla to meet up with the AEUG forces at Kennedy Spaceport. Kai informs Hayato that Quattro is indeed Char. Apolly attempts to launch an ancient Space Shuttle to evacuate the Jaburo escapees to the Argama.

The Titans' airship Sudori pursues the Audhumla. Amuro Ray and Katz escape from Federation spies that have been keeping an eye on Amuro since the One Year War and join up with Karaba. Cyber Newtype Rosamia Badam attacks the Karaba ship, and Amuro aids in the battle. Char and Amuro meet for the first time since their battle at A Baoa Qu.

Amuro learns that Hayato intended for Amuro and Katz to join him. Beltorchika Irma arrives on the Audhumla. The Sudori chases the ship over San Francisco and Rosamia heads out to attack. Katz steals the Gundam to fight Rosamia and Kamille and Char head out to defend him.

The Audhumla heads for a base covered in heavy fog where a shuttle is waiting to transport Char, Kamille, and Katz back to the Argama but the Sudori launches an attack. Katz convinces Char to leave for space with him while the rest escape back to the airship. Another letter from Kai gives Hayato his next move.

The Sudori gets reinforcements with the Psyco Gundam and pilot Four Murasame. Hayato and the Karaba attempt to meet up with Kai's contact in Hong Kong. Kamille fights the Psycho Gundam in an attempt to stop the destruction of the city.

Four and Kamille meet each other in person and begin to understand each other. Ben Wooder of the Sudori takes Mirai hostage and plans to keep attacking Hong Kong until the Audhumla surrenders. Amuro offers himself as an exchange for Mirai, and Kamille helps hold off the attack during the rescue attempt.

Kamille learns that Four doesn't have any memories and they share a kiss. The Audhumla prepares to leave Hong Kong while Ben Wooder attempts to pilot the Psyco Gundam. Four takes over piloting and Kamille and Amuro fight against her.

Hayato plans to attack the Titans' base in New Guinea to steal a shuttle for Kamille and Amuro to return to space, as the Argama has returned to Earth orbit. The Psyco Gundam continues in its pursuit of the Audhumla, but Four soon turns on Wooder and the Sudori to help Kamille return to space.
