Stopping a holdup at a convenience store, rescuing hostages from a bank robbery, saving a dog from a burning building, and bringing in a fugitive from justice are all in a day's work for Federal Agent Zach Taylor-until a chance encounter with his former girlfriend, Erin McShane, a television journalist hot on the trail of a popular Congressman with ties to organized crime, stirs up feelings he thought were long gone.

Meanwhile, a bag of rare blue diamonds stolen from Greek Jews during the Holocaust holds the key to bringing down a modern day Miami crime lord selling high-tech weapons to terrorists. Zach goes undercover when a key Government witness is murdered and his partner seriously wounded, teaming up with his former prisoner, Matt Crawford, and a mysterious, beautiful diamond dealer known only as "Malone." Using the blue diamonds as bait, Zach must penetrate the Don's inner circle, gather evidence, and re-establish the government's case.
