At night in Kirkuk, Iraq, a firefight breaks out with friendly forces on each side; one Marine dies; each side says that the other side fired first. Harm and Mac investigate; the widow approaches Mac with some background material. Attention turns onto a retired Marine sergeant major who now works for a private firm under contract to the DoD; the SecNav orders his recall to active duty and his trial at court-martial; Mac prosecutes, and Harm defends. Bad intel presents a problem. Harm calls the CEO of the civilian firm to the stand, and he exposes information extremely damaging to the firm. Mattie continues to improve her relationship with her father, but without ditching Harm.
