The Bone Yard

The NCIS team attends a crime scene and end up finding multiple remains among the wreckage despite the Army CID originally insisting that the whole event was nothing more than an accident. When one set of remains is revealed to be an FBI agent who was working undercover and who also receieved a very savage beating before his death, the team realises that they've stumbled upon a dumping ground which the mob have been using for eighteen years to dispose of their victims. The FBI suspect an agency mole is responsible for the exposure and subsequent death of the murdered agent, and it appears as though Fornell is being set up to take the blame for what's going on while the real mole goes undetected, knowingly jeopardising the lives of the FBI Agents and personnel along the way. Unwilling to let Fornell take the fall, Gibbs sets out to find the real mole and clear Fornell's name, using tactics that shock his team.
