The video shows a person paying for a ride through the turnstile at a subway station, and then proceeding onto the train. There are multiple turnstiles in a row and several people are exiting the train in the background. The person in the foreground taps a credit card on the card reader, the light turns green, and the turnstile rotates. The person then walks onto the train. The train is marked "Subte" on its side. There are yellow and blue markings on the floor in front of the turnstiles.
