Three years after the defeat of Gargoyle and Neo-Atlantis, a new threat has surfaced bent on bringing the world under his control. Geiger, using advanced robot technology, is attempting to begin a world war, and take control of the devistated world after the destruction has stopped. Once again, Nadia and Jean must fight to save the world, only this time from itself.

Agerna is a planet rich in Vizorium, the one mineral necessary to space travel. So when a series of mysterious attacks on mining operations has the governments of the world pointing fingers and blaming each other, the World Welfare & Works Association naturally sends in their top agents to investigate. But are the lovely angels up to the task of stopping a mad scientist bent on taking a long dormant alien race to its final evolutionary form? Throw in a thief who's hunting a bottle of World War II-vintage wine and it's a safe bet that nobody on the planet is safe. It's more chaos, more mayhem and even more destruction than ever before as the Dirty Pair take on their wildest case yet!

The Dirty Pair are travelling to the planet of Ookbar in search of a missing girl. Kei and Yuri have traced Missinie to the forest of Nolandia, but their investigations have stalled thanks to the less-than-helpful Chief of Security. But the Dirty Pair have never let a little bureaucracy stand in their way.
