After a seemingly happy and successful Navy Lieutenant appears to have taken her own life, Gibbs and the team conduct a thorough investigation, interviewing family and friends from her past and present.

After the body of a missing Navy commander is found, Vance orders Gibbs and the team to work with former FBI Agent Tobias "T.C." Fornell, the private investigator who was hired to locate him. Also, Bishop and Torres interview convicted investment advisor Albert Hathaway when the victim is linked to his highly publicized trial.
