While Gibbs and Tony man a protective detail for the SecNav, a gunman shoots the secretary in his chest and inflicts what appears to be a serious injury; the NCIS starts a quiet investigation, trying to avoid media attention. Vance and Gibbs join the victim at his hospital, where they take part in an unusual gathering. Shortly afterward the gang confers in the MTAC with Vance and Dr. Ryan (the psy-ops wizard); the team has orders to investigate a huge blackmail scheme with profound implications related to national security for the present and for years to come. Ziva and Ryan's lead investigator find a body; Abby and McGee make contributions; Gibbs and Ryan find computers running without people; the three musketeers watch the dynamic duo; Tony and Ziva grab an unkempt hacker and her gear. Gibbs figures it out, then he nabs the bad guy. Ryan invites Gibbs to play charades.
