Lieutenant Commander “Gunner” McCormick is assigned as an intelligence officer to Carrier Strike Force 10, being deployed to the Yellow Sea at the invitation of South Korea for joint exercises with the US Navy. During his pre-deployment briefing, he discovers a TOP-SECRET MEMO revealing rumors that the North Koreans may still be holding a handful of elderly Americans from the Korean War in secret prison camps.
As it happens, Gunner’s grandfather, who was a young marine officer in the Korean War, disappeared at Chosin Reservoir over 60 years ago and is still listed as MIA in North Korea. Sworn to silence about what he has read, the top-secret memo eats at him. Gunner decides to spend all his inheritance and break every military regulation in the book to finance his own three-man commando squad on a suicide mission north of the DMZ to search for clues about the fate of his grandfather. Risking his career, his fortune, and his life, Gunner will get his answers, or he will die trying.
