NCIS Season 7 Episode 7

Jogging military jocks find the corps of civilian MD Elan Cirreux, expertly shot twice to cause and stop torturous, fatal bleeding. The director recognizes the trade mark MO of his 20 years Nemesis, lethal North Korean agent Lee Wuan Kai. It soon turns out she targets not (just?) his family, but also the Washinton representative of her own government, which she has turned on and vice versa.
