Set 10,000 years in the future, looking into the past (our present), the mermaid archeologist of Sunken Cities dives into depths of the Gulf of Naples. Baia - an ancient Roman town situated on the northwest shore of the Gulf of Naples, currently underwater. Under the waves, the hedonistic resort of Baia unfolds as the mermaid swims: the sunken hallways, strange scaffoldings, sculptural figures of destroyed empires, mosaics of the sea floor - Roman ruins taken by the sea owing to local volcanic activity.
