With Plato's lost Dialogue safely in their grasp, Indy and Sophia are off to Morocco where they are pursued by a bunch of screaming Nazis and an oily new character named Omar Al-Jabbar, whose favorite mode of transport is a hydrogen balloon. Indy and Sophia manage to "liberate" the hydrogen balloon from the fat and sleazy Al-Jabbar in order to escape --problem is, neither of them knows how to pilot the damn thing! Eventually, of course, they get to Crete, go exploring the ruins of a labyrinth and wind up in the map room of the legendary Atlantis! How much do you want to bet those pesky Nazis aren't too far behind?
