Censor (2021)

Great Britain from the 1980s. The first Ined works in the censorship committee, where he conscientiously cuts category B films, protecting the public from bloody details. She is offended when she reads in the newspapers that the censors are not working well and that another murder was caused by a kind of slasher. One day, another movie reminds her of the events of her own past, and the actress who plays in it looks very similar to her missing sister.
