On the day of the ceremony marking the transition from the A.D. to the Universal Century calendar, the space station Laplace, official residence of the Earth Federation prime minister, is destroyed by a terrorist bombing.

Evading Marida, who has come to take Audrey back to the Garencieres, Banagher finally manages to get Audrey to the mansion in Magallanica where she hopes to meet with Cardeas, the current head of the Vist Foundation.

The negotiations between Cardeas and Zinnerman break down as a mobile suit battle begins inside the colony, claiming the lives of Banagher's classmates.

After repulsing the Kshatriya, Banagher loses consciousness, and along with the Unicorn Gundam, he is retrieved by the Earth Federation Forces warship Nahel Argama. The ship has also rescued Audrey, as well as Takuya and Micott.

Daguza has taken Mineva (or Audrey) hostage, but Frontal rejects his demand for a ceasefire and declares that he will sink the Nahel Argama. In order to save Audrey, Banagher sorties in the Unicorn Gundam.

Removing his mask and revealing his face, Frontal requests the cooperation of Banagher, who can activate the Unicorn Gundam. When Banagher refuses, Angelo berates him for killing one of his subordinates.

Together with the ECOAS special forces group, the Nahel Argama of the Earth Federation Forces' Londo Bell unit begins an operation to recapture Banagher and the Unicorn Gundam.

Marida, now a prisoner of the Federation, tells Banagher to keep on saying, "Even so..." She says that he has the power to awaken another system that sleeps within the Unicorn Gundam.

The Unicorn Gundam reaches the wreckage of Laplace, and the La+ Program's seal is broken. A speech given 96 years earlier by Ricardo Marcenas, the first prime minister of the Earth Federation government, begins playing back.

After saving Banagher and the Unicorn Gundam, which were falling toward Earth, the Garencieres crash-lands in the Western Sahara. Meanwhile, Zeon remnants who have been hiding on Earth launch an attack on the Earth Federation capital.

As they cross the desert, Banagher learns of Zinnerman's tragic past, and how his family were killed by the Federation Forces. He decides to head for the Torrington base, where new information will be disclosed.

The Zeon remnants have begun a battle at the Torrington base in Australia, where a colony once fell, in order to obtain the coordinates to the Box that will be revealed there.

The Garencieres launches an operation to rescue Mineva and Marida, and Alberto orders Marida to stop them. Banagher changes the Unicorn Gundam into Destroy Mode and confronts the Banshee.

With Banagher, Mineva, and the others aboard, the Garencieres takes off for space. It suffers engine trouble en route, but Banagher refuses to give up.

Now on the run from the Federation Forces, the Nahel Argama has taken the desperate step of forming a joint front with the Sleeves.

Banagher is despondent now that Full Frontal has learned the final coordinates to Laplace's Box. Marida encourages him, saying that his chance will come if he holds onto his dreams.

As the Nahel Argama rushes toward Industrial 7, its course is blocked by Sleeves mobile suits. Unless it can break through the enemy lines, Full Frontal will be allowed to obtain Laplace's Box.

Banagher struggles against the psycho-jammers of Angelo's Rozen Zulu. Meanwhile, as Riddhe confronts Marida, he is overwhelmed by a thought resonance phenomenon and destroys the Kshatriya Repaired.

Banagher's great-grandfather Syam Vist has been waiting for him and Mineva at Magallanica.

As Full Frontal attempts to seize Laplace's Box, Gael's Silver Bullet stands in his way, only to be crushed by Frontal's overwhelmingly superior firepower. Seeing Gael's plight, Banagher summons the Unicorn Gundam.

An article of the Charter of the Universal Century entitled "Future" records the fact that humanity set out into space with the expectation of new possibilities.
