Kidou Senshi Gundam 00

Synopsis

With the Ptolemaios undergoing maintenance, the members of Celestial Being take a day off on Earth. Meanwhile, the Union, AEU, and the HRL holds a secret meeting to discuss plans for "Project G", a special initiative to capture the Gundams under the guise of a joint military exercise. Information later comes in that forces from the three supernations will converge in the Taklamakan Desert with a high risk of spreading nuclear radiation around the world if careful measures are not taken. Celestial Being decides to intervene, fully knowing the true objective of the enemy's plans and that they are not only extremely outnumbered, but that they may not return at all. Meanwhile, Setsuna takes a short detour to Azadistan to ask and listen to Marina's opinion of why the world is so distorted.
