In Washington, DC, a man, Michael, on an 11th-floor ledge, threatens to jump; the Metro PD calls the NCIS; Gibbs and company respond and investigate; Abby says that Michael is a Navy lieutenant. Gibbs goes onto the ledge and talks with Michael, who gives Gibbs a hand and allows him to help him back down; then someone shoots the jumper, who falls to the ground and dies; the gang continues to investigate. Tony and McGee speak with Michael's civilian shrink; Abby says that the last call to Michael's cellphone originated in the headquarters of the NCIS; the Gibbs team temporarily gets another member. The gang identify a mole and catch it, then Gibbs makes a difficult telephone call.
