At 02:00 in US territorial waters near Norfolk, Virginia, an inspection party from a Coast Guard cutter steps aboard an unidentified foreign-flag cargo ship; no crewmember is visible, but a hidden gunman shoots to death a petty officer. Under joint jurisdiction the NCIS and the CGCIS investigate; Gibbs, the gang, and Borin go to Norfolk and to the towed ship at the Naval Station. While examining the body, Ducky hears tapping sounds; the team then find a hidden Lebanese family of four, for whom the father requests asylum. Abby tells Gibbs that there was no crew other than the family; the SecNav enters the picture, as does a woman lawyer of Muslim extraction. The mother and Ziva identify with each other, but the father's past catches up with him. Tony takes off his pants for Abby, who makes a startling discovery. Borin, Gibbs, and the gang prevent destruction, hold one bad guy and grab the second one, and serve justice. Gibbs says that he's not lonely because he has kids.
