A first-person perspective video shows a person walking down a concrete staircase. The person is wearing white sandals and carrying a white bag. They are also carrying a colorful purse with a chain strap. Ahead of the person on the stairs is another person wearing a gray sweatshirt and blue jeans, carrying a black bag. Another person wearing a white shirt and black pants is visible further up the stairs. The stairs have a yellow line painted along the edge of the steps. Metal railings are visible on both sides of the stairs. The environment appears to be an indoor public space, possibly a subway station or a shopping mall. The video is shaky and appears to be filmed while moving.
