The video begins with two swimmers in a pool, one wearing a black swim cap and goggles, and the other wearing a blue swim cap and goggles. They are both in the water, and the camera is positioned above the water's surface. The swimmers are seen swimming towards the camera, and the camera angle changes to show them from below the water's surface. The swimmers are wearing black swimsuits, and the water is a clear blue color. The video captures the swimmers' movements and the bubbles they create as they move through the water.
