After Hua Mulan, a high level virologist from a government controlled biological laboratory in Wuhan, China, defects, the Black Water organization is tasked by the Department of State with getting her safely to the United States so she can testify regarding the Bio-weapons programs the People's Republic of China (PRC) is developing. After being brought to America by Dark Water, Black Water's covert international enforcement division, she is turned over to the domestic division, Muddy Water. General Gene Barker, former commander of Marine forces in Vietnam, calls in Jim Lashley, a former Marine Long Range Reconnaissance Patrolman and later an F-4 pilot flying missions in Vietnam, to take over safeguarding the lady. Knowing that the PRC will eventually determine that Hua is missing and will be sending someone to eliminate her before she can testify, Jim is faced with an almost impossible task. To keeping an unknown assailant, or assailants, from killing her or anyone in their path, Jim has to develop plans to draw out them out and eliminate them before they can do so. Once he determines who they are, he must also convince them that Hua is dead and wait for them to report back to Beijing before he eliminates them. As all of his well laid plans start to crumble, Jim is forced to enact some controversial methods to save Hua while ensuring that no further attempts will be made on her life.
