The NCIS team investigates when a Petty Officer commits suicide after being institutionalized for a nervous breakdown.

Gibbs and the team are stunned when Ducky tells them that the Petty Officer, who claimed to have a stalker, was in fact murdered and did not commit suicide. With the help of FBI Agent Fornell (guest star Joe Spano), the team’s investigation reveals the Petty Officer was a victim of a twisted love triangle involving her C.O., who was being investigated by the FBI for kickbacks received from Navy contractors.
