Umm Sibyan: Pitch Black (Ümmü Sıbyan: Zifir) (translated)

Ümmü Sıbyan: Zifir is a 2014 Turkish horror film directed by Efe Hızır. Shot in Turkish, the film was seen by 132,902 viewers in Turkish cinemas, making it one of the notable examples of domestic horror cinema. Starring Berkan Bulut and Melisa Akman, it transplants folk beliefs about jinn and possession into a modern school setting.

The story begins when a group of high school seniors, looking to escape exam pressure, secretly enter their school at night. One of the teens suggests summoning the spirit of Kevser, a student who committed suicide at the school years earlier. What starts as an innocent game soon spirals out of control, for the entity they believe they have called is actually a jinn known as Ümmü Sıbyan, said to haunt pregnant women.
