Lilly returns to her last case before joining the Cold Case Squad as she re-investigates the brutal triple homicide of a restaurant owner and his family, murdered in the restaurant bathroom in 2003. Also the other team member have personal reasons to closing the case; Jeffries grew up in the predominantly black neighborhood while Vera was the one assigned to the case when Det. Rush left.

When human remains are found outside a former state prison, the team re-opens the 1968 case of a dead inmate, murdered on the night Johnny Cash's Folsom Prison Concert was broadcast to prisons throughout the country. However, when it's revealed that the bones don't belong to the person everyone had assumed, the team must start the probe anew by first identifying who the victim was.
