NCIS

The NCIS team begrudgingly joins forces with the FBI when they identify the remains of a man on a Marine base as a serial killer the FBI has been hunting for 12 years.

When a highly classified robotic vehicle called "Otto" causes the death of a Navy Lieutenant, Gibbs and the team initially think the cause of death is suicide.

Gibbs and the team rush to a scene where a high-level intelligence officer was murdered, only to discover that the crime took place three days earlier and was "investigated" by the local authorities.
