While testing an experimental robotic driverless SUV, a woman Navy lieutenant becomes trapped inside the car, and she dies of carbon-monoxide poisoning. Gibbs and company, finally unable to avoid the dreaded sexual-harassment training lecture, attend, but a phone call summons them to investigate the death. The victim's civilian co-workers tend to suspect suicide, but McGee suggests otherwise; one part of a surveillance tape has become erased. Tony and Ziva make a startling discovery; Abby becomes stuck in an uncomfortable situation, but Gibbs rescues her, although McGee does not. Tony sings a song and sees Jeanne again, and the gang get the answers and the bad guy.
