London, 1974. As Britain prepares for electrical blackouts to sweep across the country, trainee nurse Val (Rose Williams) arrives for her first day at the crumbling East London Royal Infirmary. With most of the patients and staff evacuated to another hospital, Val is forced to work the night shift, finding herself in a dark, near empty building. Within these walls lies a deadly secret, forcing Val to face both her own traumatic past and deepest fears in order to confront the malevolent force that’s intent on destroying everything around her.
“While I was writing the script, I read a good description of what a ghost story classically is; a disturbed spirit has an issue that a protagonist, usually female, needs to understand and solve. Then the spirit can rest in peace. This description resonated with me. I was already telling the story from a female point of view, and wanted the female experience to inform the horror elements. But I was writing during the explosion of resistance to silence and passivity that came with the Me Too movement. And it felt like the landscape was changing to some extent. The idea that an angry spirit could neatly be put to rest, made quiet at the end of a story, felt plain wrong. This gave me an interesting trajectory.
