The video shows a group of people swimming in a muddy river. The water is murky and the swimmers are covered in mud. They are moving slowly and appear to be struggling to swim through the thick mud. The swimmers are wearing swimming caps and goggles, and some are using their hands to push through the mud. The riverbank is visible in the background, and there are trees and vegetation along the river. The video is shot during the day, and the lighting is natural.
