Conspiracy Theory

Gibbs and his team are called to investigate a possible crime when a Petty Officer named Jessica Smith reveals that she was attacked by a man wearing battle fatigues and body armour but there's no such evidence to suggest that it took place. Her therapist Lt. Witten reveals that Smith has paranoid delusions which he believes was triggered by the death of her fiancee in Iraq the month before. Things take a shocking turn when Gibbs and Kate later find Smith dead in her room, having seemingly committed suicide but Ducky later discovers the truth: she was actually murdered. With the help of FBI Special Agent Tobias Fornell, Gibbs and the team must dig deep into Smith's life and find out who was responsible for her murder.
