AND SOMEWHERE IN THE JUNGLES OF VIETNAM, A U.S. SOLDIER LIES IN A FORTY-YEAR-OLD GRAVE.

Commander Will Coburn's NCIS team is investigating the carjacking and assault of a young Marine and his wife. All evidence points to Bobby Lee Gant, the son of notorious criminal and suspected international drug smuggler Victor Gant. When NCIS agent Shel McHenry is wounded during a botched arrest, the team rallies around him as Victor threatens retribution.

Meanwhile, in west Texas, Shel's father, Tyrel McHenry, struggles with his own demons as buried secrets from a war long since fought come to light. The path he chooses will change his—and Shel's — life forever.
