Just when Lupin, Jigen, and Goemon wonder what she's called them for, Fujiko shows up, kicks their sukiyaki, has a firefight, and leaves them a present: the detonator plug to a pint-sized A-bomb. An aircraft museum which is restoring old aircraft is merely a cover: in fact, the aircraft a flying merchant of death, with an A-bomb manufacturing plant housed in its wings. The head man, Lonebach, tries to seduce Fujiko by telling her that he will make her his first wife. Will Lupin let him get away with it?! Let the big aerial battle begin!!
