In London, Indiana Jones is called to an emergency meeting. Mysterious sky craft have been ravaging the shipping lanes, making off with a fortune in diamonds, bonds, and raw materials. Unable to detect how the craft are powered, experts have come up with a frightening hypothesis—involving the use of psychokinetic levitation.
To get to the truth, Indy must search through a labyrinth of archaeological information reaching back four thousand years. But as he and his team move from Africa to Tibet to the American Southwest, they discover something even more astounding. A clandestine organization is fast becoming an evil, world-dominating power—and the only way to stop it is in a high-tech, no-holds-barred battle on land . . . and in the air!
