While investigating the hit-and-run death of a young boy, Seattle homicide detective Tracy Crosswhite makes a startling discovery: the suspect is an active-duty serviceman at a local naval base. After a key piece of case evidence goes missing, he is cleared of charges in a military court. But Tracy knows she can't turn her back on this kind of injustice. When she uncovers the driver's ties to a rash of recent heroin overdoses in the city, she realizes that this isn't just a case of the military protecting its own. It runs much deeper than that, and the accused wasn't acting alone.
