A group of about a dozen people are exercising in a public space at night. They are spaced out across a large, light-colored concrete plaza, and seem to be following an instructor who is not clearly visible. Most are dressed in casual athletic wear. Streetlights illuminate the plaza. In the background, there's a small gazebo-like structure with an orange roof, as well as some playground equipment. The night sky is mostly dark, with some visible clouds. The camera moves slightly, with a brief obstruction from some foliage.
