Good Cop, Bad Cop is the 142nd episode of NCIS and the fourth in Season Seven.
When Ziva's application to become an official NCIS Special Agent is rejected, Vance confronts her with the news of a Marine whose mangled and decayed body has been found off the coast off Tanzania by a fishing boat, forcing Ziva to recall a series of events that led her to the terrorist camp while Gibbs and the rest of the team race against the clock to prove Ziva's innocence when a fellow Mossad officer from Ziva's past arrives at NCIS, demanding Ziva return with him to Israel.
In Observation, Gibbs is examining photos of the crime scene while in Interrogation, Ziva paces the room, obviously restless when Ducky arrives in.
- Officer Malachi Ben-Gidon, head of the Kidon Unit and Ziva's commanding officer is introduced for the first time.
- Ziva's application to become an NCIS agent after denying for the first time eventually goes through, resulting in her becoming an official agent.
- The scene outside the window of Agent Dunham's scene is actually a part of the movie Black Hawk Down.
