To prevent nuclear annihilation, wounded Special Forces operative Jim Chapel must infiltrate a top secret Russian military base and disable an unstable supercomputer

A routine mission in Cuban waters to retrieve a hidden key code from a sunken Soviet submarine quickly changes course when Cuban officials are tipped off. It turns out that Nadia, the beautiful stranger who saves Chapel from being discovered, is actually a Russian agent, and her intel is shocking. Hidden during the Cold War, a forgotten Russian supercomputer controls hundreds of nuclear missiles, all aimed at the United States. Just one fail-safe error and America will be obliterated. And there have been glitches in the computer's programming. . . .

To disarm Hydra before it plunges the United States into nuclear winter, Nadia and Chapel must travel across Eastern Europe and infiltrate a secret base hidden deep in the steppes of Central Asia. But as these uneasy allies discover, not everyone wants the weapon out of commission.

Jim Chapel is out of his depth, and out of his element, but not out of the game.
