Gibbs, Tony, McGee, and Ducky investigate the death of a petty officer aboard a Naval vessel; later Tony and McGee screen potential replacements for Ziva; nobody in the gang has heard from Ziva, so Gibbs, Tony, McGee, and Abby all start sniffing and digging around; they trace her to a Jordanian cargo ship, which sank in a storm off the coast of Somalia, reportedly with no survivor. Tony urges Gibbs to stop Saleem, then the team makes a case to Gibbs and Vance, who reluctantly approves an "investigative" mission to Somalia, where (as a part of a plan) Saleem captures Tony and McGee, to whom Saleem administers a truth serum. Saleem also reunites Tony and McGee with Ziva, whom Saleem has tortured.
