Censor (2021)

In 1985, Enid Baines works for the British Board of Film Classification during the height of the Video Nasty controversy. Enid's co-workers call her "Little Miss Perfect" due to her strictness in recommending that violent content be cut or banned. While Enid is having dinner with her parents, they discuss the disappearance of Enid's sister Nina when the two were little. Enid's parents have since declared Nina legally dead, but Enid is convinced that her sister is still missing.
