At the NCIS headquarters a defiant and uncooperative suspect on a drug-related charge collapses and dies in an elevator while in the custody of Ziva; suddenly she becomes a suspect rather than an investigator. The rest of the team investigate. Then the director disappears after a lunch meeting; Gibbs learns that the brother of the dead suspect kidnapped the director; Tony finds her driver, dead, in the car. One of the bad guys turns against the other, then the big brother calls Gibbs and demands his brother and his heroin. The two brothers meet an aircraft, as do Gibbs and his gang. Ducky finds a congenital defect, and he rules a death of natural causes, thus clearing Ziva.
