Jack Kempson started out as an idealistic cop. Thirty years on, he remains relentless in tracking down villains, but has lost confidence in his moral barometer. He turns a blind eye to the dubious methods employed by some of his contemporaries — prepared to let dodgy means be justified by the noble end.

When a deadly assassin hijacks a passenger train, he threatens to detonate a deadly can of poison that can wipe out an entire city, if he isn't given a 25 million dollar Ransom. While the cops are attempting to thwart the madman, they decide to call Former DEA agent Paul Blake, the one man who can possibly stop the fiendish plot.
