A close-up of a human eye with a glowing blue iris transitions to an underwater scene where a humanoid figure with gills and webbed hands swims through dark water. The figure, a merman, is shown from behind, then from the side, and finally faces the camera as it ascends, before being grabbed and pulled underwater by a large, dark sea creature, resulting in a chaotic struggle with bubbles and a blurred, distressed face.
