In 1972 Major Jake Hammer, an army ranger, is sent on a mission to search for answers involving ambushes of military units. During a battle Jake captures a North Vietnamese colonel named Duc Toe. Jake finds stolen TOP SECRET documents in the colonel's possession detailing military operations and troop movements. Jake orders his brother Marvin to transport the evidence back to Saigon for investigation. Marvin's Cobra Helicopter is blown up killing Marvin and his co-pilot. In the meantime Colonel Duc Toe escapes. In 1975 Jake returns to Saigon on a special ops mission to recover stolen gold reserves. During his return Jake falls in love with Deanna Templeton, an embassy administrative assistant. She helps Jake find out his brother's death was no accident, and was covered up by the military. The mystery further leads Jake to discover a drug pipeline between Colonel Duc Toe, military and embassy officials in Saigon and, on the home front, the anti-war movement and the New York mob.
As North Vietnam undertakes the final invasion of South Vietnam, Jake races against time to help his friends escape and serve final justice to those responsible for espionage, treason and murder.
