The movie "Boston Strangler" 2023

US East Coast June 1962: In the state of Massachusetts, four women are murdered in about two weeks. While the police seem to be groping in the dark, journalists Loretta McLaughlin (Keira Knightley) and Jean Cole (Carrie Coon) take on the cases and make connections that indicate the same perpetrator is always involved. By early 1964, nine more murders had occurred, always following a similar pattern: the perpetrator gained access to women's homes and strangled them there, usually with an item of clothing. In their investigations, the reporters not only have to contend with their superiors and the sexism of the time - there are indications that the authorities are working deliberately sloppily, and when a man finally confesses to the crimes, doubts remain as to whether the person is actually the murderer.
