As the condition of Dr. Leon Casteel (who is dying of radiation poisoning) worsens, Tom Ryan makes a discovery. Not only was the Doctor working for the terrorists behind the attempt to destabilize our government, he has constructed a WMD which the terrorists plan to deploy in a major U.S. city. But Dr. Casteel refuses to divulge the location of the device unless the Unit can save his family, who are being secretly guarded by the terrorists at a plush resort until the attack is completed. With the clock ticking, Mack, Bob, Grey & Bridget must rescue the doctor's family in time to avert a catastrophe. The women, struggling to find their footing in this new world, are thrown yet another curve ball when Tom Ryan gathers both men and women to inform them of what he has just learned: the real reason they've been relocated, and what the women's missions are. Just as their husbands are warriors the women must become warriors, too.
