A neighbor opens a small package containing two human eyeballs mistakenly delivered to her mailbox but addressed to a petty officer attending a school at the Dam Neck Annex of NAS Oceana, near Norfolk and Virginia Beach. The neighbor reports, and Gibbs and company investigate. The shipment originated in Ciudad del Este, Paraguay, near Brazil and Argentina. While doing surveillance on the intended addressee, Kate and Tony get a big surprise. Gibbs and Kate interview an instructor, and Gibbs contacts a fellow Marine. Kate and Tony go to Paraguay, and they encounter much intrigue and make some discoveries; they find the instructor, then they return to Washington.
