While working on a top-secret research program for the US Department of Defense in the freezing waters off Japan, a leading scientist turns up dead, eaten by a monster shark. US Air Force OSI Special Agent Vin Cooper is hurriedly dispatched to investigate. Cooper, however, has barely begun when he's pulled off the case to look into the death of an old military buddy who died while making a routine parachute jump. Both cases suddenly collide when Cooper finds himself having to parachute out of a plane and into the night-time skies of a hostile Pakistan. His mission: to recover stolen US Defense biological technology. The stakes: to prevent a nuclear war between Pakistan and India that could engulf the world. The problem: Cooper has to jump alongside a soldier he suspects is a killer.
