A brilliant Air Force weapons scientist dies while skydiving. A handwritten suicide note is the only item found in his empty parachute pack. Searching for answers, his eldest son is brutally murdered, and another Department of Defense researcher dies in a horrific explosion. Marine Lieutenant Jack Gallaher demands to know what caused the tragic deaths of both his father and his older brother. His relentless pursuit leads him to a shocking conclusion: a submarine-based laser cannon and an orbiting satellite reflection mirror have been hijacked from the American military by a trusted source, and ownership has been transferred to the Russian Federation Navy. Held captive onboard one of the Russian Federation's most advanced nuclear-powered guided missile submarines, Gallaher must fight against time to destroy the laser weapon before it can be unleashed against the U.S. and Allied forces. It will become Gallaher's most daunting challenge.
