The Power (2021)

East London, January 1974. Due to large-scale miners' strikes, power outages occur at night and the country is literally plunged into darkness. And the young nurse Val has her first day at the hospital in the big city. Almost immediately, the girl feels anxiety, as if something is following her from the gloomy corners, and when the strict head nurse leaves Val for the night shift, the dark entity begins to slip more and more.
