The video shows three people snorkeling in clear turquoise water near a rocky, green island. One snorkeler is wearing a black wetsuit and mask. Another is wearing blue swim trunks, an orange shirt, a mask, and a snorkel. A third snorkeler is wearing a black mask and a black top, with what appears to be a camera or a phone attached to their arm. All three are swimming and appear to be looking at something underwater. The sky is clear and blue.
