Stephanie Maddox works her dream job policing power and exposing corruption within the FBI. A single parent, Steph has missed a lot of school events, birthdays and vacations with Zachary, who is now a teenager.

Then comes a knock at her front door --- a colleague on the domestic terrorism squad, who utters three devastating words: “It’s about Zachary.”
