A group of people are engaged in a synchronized dance or exercise routine on a concrete dock or pier next to a large, multi-deck river cruise ship. Many passengers are visible on the ship's three main decks, observing the activity from their balconies and railings. Some passengers on the lower deck are wearing red shirts. The sky is partly cloudy, suggesting it's daytime. In the foreground, a person wearing a bright orange life vest runs from left to right. The event appears lively, with participants on the ground actively moving and spectators on the ship watching.
