Knocking (2 Stars)

This is the 33rd film in the Stuttgart Fantasy Film Festival.

Molly is a woman who suffers from paranoid delusions. She's recently been released from hospital, but she's still in regular contact with her doctor. She has an apartment on the eighth floor of a large building. She frequently hears knocking on the ceiling. She visits the people who live above her, but everyone says there isn't anyone knocking. Sometimes she hears a woman crying for help. She rings the police, but no evidence of a trapped woman is found. Nobody believes her because of her history of mental health issues.

I found the film disturbing. It's not a subject matter that I like to watch.
