Jefferson Pierce is a man wrestling with a secret. As the father of Anissa and Jennifer, and principal of a charter high school that also serves as a safe-haven for young people in a neighborhood overrun by gang violence, he is a hero in his community. Nine years ago, Pierce was a hero of a different sort. Gifted with the superhuman power to harness and control electricity, he used those powers to keep his hometown streets safe as the masked vigilante Black Lightning, but he left the Superhero days behind. Almost a decade later, Pierce’s crime-fighting days are long behind him…or so he thought.

As the community struggles with the violence surrounding them, a glimmer of hope appears: Is Black Lightning back? Lynn Stewart, noticing the changes in the community, is also left wondering.
