NCIS: Season 6, Episode 9

6 - 9: Dagger

Agent Lee becomes a reluctant participant in helping the NCIS team stop a top secret defense plan from being stolen. Lee is used as bait to capture her contact, Ted Bankston, who also tells of having a family member held captive. Bankston turns out to be the mastermind in the caper and takes Lee hostage, as Gibbs corners them on a bus. Gibbs receives minor wounds in the ensuing exchange. Lee gives a signal to shoot and is shot and killed along with Bankston. Gibbs takes Lee's badge and gives it to her step sister who was found alive, as the team sorts out Lee's ultimate role in the plot.
