In West Berlin, Amy Brecker, an American intelligence officer, takes a chance on a walk-in informant who says that the Soviets are going to simulate an "accident" that will cripple America's space-based defense program.

From a Soviet silo on the Sea of Japan, a single missile rises. A hotline communique from Moscow insists that a mistake has been made; the Soviets are doing everything in their power to abort the "test" flight.

Deep inside Cheyenne Mountain at the Aerospace Defense Command Center, all eyes watch its trajectory: a collision course with America's manned space lab.

If the U.S. chooses to intercept and destroy the Russian missile, the attempt must not end in failure . . . the future of Ameria's entire space-based defense hangs in the balance. Only one U.S. anti-satellite weapon can foil the opening gambit of what might be a Soviet First Strike -- and only Amy Brecker and her "hot stick" pilot have enough of the Right Stuff to use.
