The document outlines the narrative structure and technical codes used in a trailer for a psychological horror film. It follows classic trailer conventions like establishing shots of the location in the beginning to set the scene, then introduces the main characters of the villain and victims. Tension is built through enigmatic shots of the villain and shots that tease problematic events without showing the full extent. The climax further complicates things through short, teasing shots of victims being attacked. Finally, the "convincer" at the end leaves the audience with a question to encourage viewing the full film. Technical elements like camera angles, editing, sound, mise-en-scene are described to maximize suspense, tension and identify characters.
