The video shows two people swimming underwater. They are holding onto a rope and appear to be pulling themselves up. The water is a dark green color, and the visibility is somewhat low. The two individuals are wearing black wetsuits and appear to be in good physical shape. They are moving slowly and deliberately, using their arms to pull themselves up the rope. The rope appears to be attached to a boat or some other structure above them. The video does not have any visible title, subtitle, or other informative text.
