The murder of two former private military contractors necessitates an NCIS investigation. A prostitute at the scene provides evidence that another contractor might have been their target. Sam and Callen locate the contractor being targeted and question him. He claims to have information that has put him in jeopardy from his former firm. Deeks and Granger question another private contractor and discover that their target killed a bunch of women in Afghanistan and they were trying to stop him. Nell, who has been left to protect the target, comes under attack by the man. Sam and Callen arrive in time to save her. Meanwhile, Kensi suspects Sabatino might be the mole and enlists Nell (and Eric) to help investigate. Sam sets Callen up on a date.
