A Petty Officer along with the original car's driver are both found dead on a country road. At first, it appears to be an ordinary car accident but the team soon discover evidence strongly suggesting that the Petty Officer was murdered. During an autopsy, Ducky later finds evidence that the woman was pregnant and gave birth just before she died, sending the team in a desperate race against the clock as they not only attempt to arrest the killer but also recover the missing baby before it's too late while Tony tries to come to terms with recent events.
