The video begins with a person swimming underwater, wearing a red and black swimsuit. The camera then cuts to a large whale swimming in the ocean. The whale's body is mostly gray, with a white underbelly. The whale's tail is visible, and it is moving through the water. The camera captures the whale from different angles, showing its size and the smoothness of its skin. The water is a deep blue color, and the lighting is natural, suggesting that the video was taken during the day.
