Jefferson Pierce has a secret. As a private high school principal and father of two, Jefferson also protects the small people of his neighborhood in New Orleans from the violence that surrounds the city. Nine years ago, Pierce was somewhat of a hero. He wore a suit of armor and had the ability to control electricity, defending the streets of his hometown under the Black Lightning mask. Over time, as this second identity damaged his family relationships, he left his superhero days behind, became a principal, and settled into family life. He preferred to help the city without his superpowers, watching his daughters Anissa and Jennifer transform into strong young women; even if he couldn't improve his relationship with his wife Lynn... Now, nearly 10 years later, Pierce's days of fighting criminals will return. As crime and a corrupt system spread like a fire that’s hard to extinguish, Jefferson decides to take on the regional gang known as “100.” He will now save not only his family but the souls of everyone around him.
