Two storylines occur simultaneously on the vessel: one on deck and one beneath. The narrative on deck involves the process of casting a 25-ton petroleum jelly sculpture (one of Barney’s signature materials), which rivals the scale of a whale. Below deck, the two main characters participate as guests in a tea ceremony, where they are formally engaged after arriving on the ship as strangers. As the film progresses, the guests go through an emotional and physical transformation slowly transfiguring from land mammals into sea mammals, as they fall in love. The petroleum jelly sculpture simultaneously passes through changing states, from warm to cool, and from the architectural back to the primordial. The dual narratives, the sculptural and the romantic, come to reflect one another until the climactic point at which they become completely mutual.
