Lilly re-investigates a brutal triple homicide, the last case she worked before moving to the cold case squad.

When the prime suspect proves to be innocent, Rush and the team re-open a 2003 triple homicide at a now-condemned restaurant in a blighted inner-city neighborhood. The diner had been a neighborhood oasis before the owners and their 17-year-old son were brutally murdered. The original crime scene was Rush's first case, but she was soon called off to join the Cold Case squad, leaving Vera as the officer in charge. It quickly becomes clear that Vera's investigation was sloppy, which infuriates Jeffries, who grew up in the neighborhood.
