Jefferson Pierce (Cress Williams), respected educator and father of two, is also Black Lightning, superpowered protector of Freeland. And he doesn't fight alone. He is joined by his superpowered daughters, Anissa (Nafessa Williams), aka Thunder, and Jennifer (China Anne McClain), aka Lightning, as well as his ex-wife, metahuman expert Lynn (Christine Adams). Together, the Pierce family combats the ills eroding their city, including a menacing gang that calls itself The 100 and infamous gangster Tobias Whale (Marvin Jones III). Worse, Freeland has been plagued by government-sponsored experiments and drug trafficking, creating metahumans and addicts while making Freeland the target of a dangerous foreign power, Markovia. Fortunately, the family still has allies in their fight: former covert superspy Peter Gambi (James Remar) and Jefferson's neighbour, the scrupulously honest deputy police chief Bill Henderson (Damon Gupton).
