The film is a neo-noir crime thriller that uses several conventions of the genre, such as low-key lighting, unusual camera angles, and an urban nighttime setting. It features a detective protagonist who challenges the convention of typically being male. The opening scene shows a crime having occurred. While most conventions are followed, such as costumes, music, and clues being left by the murderer, the film challenges conventions by having a female detective as protagonist and starting after the murder occurs rather than showing it. The film represents women, who make up a large part of the audience for psychological thrillers and true crime media. It deals with the issues of homicide, murder, and city crime.
