In "The Power" based on Naomi Alderman's feminist sci-fi book, all teenage girls in the world develop the power to electrocute people at will. It's hereditary, it's inbuilt, and it can't be taken away from them. Coming alive to the thrill of pure power: the ability to hurt or even kill by releasing electrical jolts from their fingertips, they rapidly learn they can awaken the Power in older women. Soon enough nearly every woman in the world can do it. And then everything is different.

The subversive, multi-stranded narrative follows a series of characters including Allie (Halle Bush), a vulnerable American foster kid who reinvents herself as a faith leader; Roxy (Ria Zmitrowicz), the daughter of a London crime boss, who revels in her new abilities; Tunde (Toheeb Jimoh), a Nigerian journalist reporting on seismic global change; and Margot Cleary -- Lopez (Toni Collette), Mayor of Seattle; loving wife and doting mother to three kids.
