A red crab with wide eyes looks up in alarm at a large hourglass in a dark underwater setting, then shifts to a side view with a worried expression, and finally peers through a pair of goggles with bubbles rising around it. A woman in a black wetsuit and blue flippers swims over a coral reef, followed by a point-of-view shot of a woman in a pink bikini swimming underwater, and then a close-up of a woman's legs and back as she swims underwater.
