NCIS: Season 2, Episode 5

2 - 5: The Bone Yard

The NCIS team attends a crime scene, and end up finding multiple remains among the wreckage. When one set of remains is revealed to be an undercover FBI agent, 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's being set up to take the blame for what's going on. Gibbs then sets out to find the real mole and clear Fornell's name, using tactics that shock his team.
