For Detective Vic Lenoski and his partner, Liz Timmons, the past is closing in.

With a new murder to solve, Vic and Liz learn the victim is the son of Jake Kittery, one of Pittsburgh's best-known union organizers, whose feud with a now-retired police officer stretches back thirty years. Did the retired police officer finally get revenge for the death of his own son during one of Jake's union protests?

At the same time, Liz is questioned by a PI about the mysterious circumstances surrounding her husband's disappearance during Hurricane Katrina. Liz is suspicious of the PI, but the ache of wanting to know what happened to her husband pushes her to risk a trip to New Orleans, and possibly her own life.

Will the past explain what happened to Jake Kittery's son and Liz's husband, or are things more recent and deadly at work?
