In 1988, a young man is gunned down on a highway after his car is hit from behind and a woman riding with him is wounded. The case was thought to be a routine carjacking until the woman disappeared from the hospital where she was being treated. In 2006, the probe is reopened when the woman is spotted in Atlantic City and she's brought in for questioning. The investigation reveals that the woman and the married victim were having an affair and planned to run away with each other.

The 1968 death of an 18-year-old girl who apparently fell down a flight of stairs backstage at a debutante ball is investigated after her mother comes forward with new information. A local art dealer, who back in 1968 escorted the victim at the ball, is accused of killing his wife by pushing her down the steps. The mother believes it isn't a coincidence that both victims died in the same way. Lilly becomes convinced, too, but there isn't any evidence to prove it.
