group of children and a couple of adults swimming in a brown-colored lake. The sky is clear and blue. Trees line the edge of the lake. A couple of people are walking on a bridge or raised path in the background. Some of the children are partially submerged in the water, while others are swimming or standing. One child in the foreground raises both arms in the air. There is a metal railing visible in the lower right of the video.
