A large cruise ship sailing on the ocean.

The ad opens with a wide shot of a large cruise ship sailing on the ocean, leaving a white wake. It then cuts to a man in athletic wear standing on a dock in front of the ship, holding weights. The scene shifts to a small boat on the water with two people, one of whom is wearing a wetsuit and glasses. The man in the wetsuit points excitedly. The boat speeds through the water, and the man dives into the ocean. Underwater shots reveal fish swimming over a mosaic floor and then a person's flippers propelling them through the water. The ad concludes with a shot of the cruise ship sailing on the ocean, with the Costa logo and tagline.
