Thriller:
Lieutenant Perry Helion is at the end of a short, unlucky Air Force career when he comes across a strange doomsday cult and their ultimate weapon: The SHIVA Compression. The SHIVA computer virus is designed to launch American nuclear missiles automatically should an enemy attack wipe out the U.S. high command. Once the released, SHIVA is all but impossible to stop. After Perry discovers SHIVA, only one higher officer, a fireplug colonel used to doing things his way, realizes that SHIVA is real. Together with the colonel and his small team, Perry must battle the deeply rooted doomsday conspiracy and stop SHIVA before it launches U.S. missiles and plunges the world into nuclear war.
