The film opens with an establishing shot of the city at night under a cloudy moonlit sky. The scene then introduces the main character, a woman, who wakes up in her bedroom disturbed by shadows on her face. She closes her open window and witnesses a domestic abuse situation happening across the street. She calls the police and the opening credits roll as the lights across the street turn off. The next scene shows a police car driving down a dark street towards the location of the abuse, setting up the murder investigation to come.
