8.30PM TUESDAY / JULY 1

A multi-millionaire real estate investor who doubles as a reserve officer is sent to serve in Iraq with US Marines and is killed by a mortar attack.

When his body is returned to Washington, his wife reveals that her husband had been in the middle of a business transaction with unscrupulous investors at the time of his death.

Because of that, she doesn’t believe that he was actually killed by the mortar attack, which is also confirmed by Ducky's autopsy, revealing that a gun shot wound was the cause of death. She thinks he was singled out: murdered by a contract killer.

Gibbs dispatches DiNozzo and the inexperienced but competent NCIS analyst Nikki Jardine to Iraq to continue the investigation, while Gibbs and the rest of the NCIS team follow leads and investigate the crime from Washington.

DiNozzo and Jardine's investigations reveal the identity of the alleged killer, however they are one step behind a renegade militia group who has since kidnapped the killer and plan to execute him. They must track down where the militia group intends to take him and intercept before the execution takes place. Meanwhile, Jardine appears to have an ulterior motive for coming to Iraq and her personal interests are at conflict with her professional beliefs.
