A maniac bomber is ruthlessly targeting Seattle, claiming civilians and bomb disposal teams alike as apartment blocks and office complexes collapse under the inpact of his ingenious, complex devices.

Calling in ex-Bomb Squad man John Pierce (SAM ELLIOT) to help them, and using computer assisted disposal techniques and virtual reality simulations, the squad comes to a horrifying realisation - the bombs are constructed with tricks and traps intended to kill the disposal teams...and the only person who would know such schemes would be fellow Bomb Squad Officer. With the police marking Pierce as their number one suspect and the bomber on the brink of the one final, cataclysmic attack, Pierce must move quickly to unmask the trigger-man behind the carnage or face taking the rap himself.
