Old man

A person in a dark jacket and gloves holds a small, cylindrical device with a red light, then the scene cuts to a young woman walking down a school hallway, followed by a close-up of a man's face, then a woman in a green top and black skirt walking down a hallway, then a man in a black jacket and glasses speaking to a seated audience, and finally a young man in a blue and white jacket confronting a shirtless man in a school hallway.
