Relena and Heero have come aboard the Libra in a last-ditch hope to talk some sense into Zechs, but he will not listen. Treize and his forces arrive, and Treize challenges Zechs to a one-on-one duel to decide the fate of the war, but Zechs refuses. Now the immense ships Libra and Peacmillion are on a collision course with one another, and the resulting collision could destroy all life on Earth. It's up to the Gundam pilots to put an end to the fighting.
