The video shows a man surfing on a river wave. He’s wearing swim trunks and is barefoot. He loses his balance and falls off the board. On a small platform next to the wave, another man in a red wetsuit is standing with a surfboard. He holds the surfboard up in the air, perhaps signaling that he’s ready to assist or take over. A crowd of people watches from the banks of the river under the shade of several trees with white flowers.
