A scene is a segment of a film set in a single location or time. It is a unit of the story. A film is made of scenes. Each scene has a beginning, a middle, and an end. It has a purpose: to advance the plot, reveal character, or establish mood. A scene can be long or short. It can be a single shot or dozens of shots. It can be a conversation, an action sequence, or a quiet moment. The scene is the building block of the screenplay.

Scenes are defined by unity of place and time. A scene takes place in one location and in continuous time. When the location changes or time jumps, a new scene begins. In a screenplay, scenes are marked by slug lines, which indicate the location and time. INT. COFFEE SHOP - DAY. That is a scene heading. It tells the reader where and when the scene takes place. The scene continues until a new slug line appears.

The scene is not the same as a shot. A shot is a continuous recording from one camera setup. A scene can contain many shots. The editor assembles the shots into a scene. The director shoots the scene. The writer writes the scene. Each contributes to the final product. The scene is the fundamental unit of storytelling in film. It is where the story happens. It is where the characters live.
