This video is a clip from the Harry Potter movie series. It shows two characters, Harry and Hermione, running through a hallway in Hogwarts castle. They are running away from something, and their faces are not shown. The hallway is dimly lit, and the camera follows them from behind as they run towards a large window at the end of the hallway. The characters are wearing their school uniforms, and the scene is tense and suspenseful.
