The wife of a deployed enlisted Marine disappears, then a second such wife also disappears; the NCIS investigates. McGee recalls having seen the bedroom of the first wife in a video clip; now he says that he saw the murder of the woman on camera, although at the time he thought that the clip was a faked one. Abby analyzes the clip, and McGee figures out the source. The two wives had gone into a porn business together online, but the cash inflow is elusive. Abby figures out what type of knife appeared in the clip, and McGee finds the money. The webmaster also disappears, but Tony and Ziva find him. The gang put the pieces together.
