Nolan Kilkenny is a former Navy SEAL who is now pursuing his doctorate in advanced computer technology. While investigating a seemingly harmless technical problem in a complex, highly secured computer network, he becomes involved in the CIA and FBI's fierce hunt for three computer-age information pirates. The ruthless, brilliant thieves have stolen SPYDER - the CIA's ultra-secret electronic intelligence gathering project that can pry open the most heavily-guarded computer networks in existence - and United States government will do anything to get it back.

Suddenly, Kilkenny is leading the search for SPYDER...and is in sharp focus in the crosshairs of those who will stop at nothing to possess the ultimate spy weapon.
