A raid by agents of the Immigration & Naturalization Service (INS) on a boat carrying Vietnamese ladies being smuggled into the USA, also nets a distinguished Vietnam-native Marine Lieutenant, who is suspected to have a part in bringing the ladies in for profit. Harm & Sturgis are assigned to see if the Lieutenants claim that he broke into the warehouse containers to steal is true, or if he really is one of the lead smugglers. They learn that when the Lieutenant was four years old living in Saigon with his mother, he was loaded onto the last helicopter evacuating people from the US Embassy in Saigon on April 29, 1975, just before the city was invaded by North Vietnam. As there was only room for 1 person left on the helicopter, his mother placed him onboard & stayed behind. He was then brought to the US & later joined the Marines, rapidly advancing through the ranks, becoming a pilot & earned great distinction for himself.
