In an alternate universe where there has never been a war or deaths. Where pirates are convinced of the existence of mermaids even though they are hiding in the depths of the ocean. Barty had always learned that mermaids were monsters that lured humans underwater to kill them. If he had one goal in his life, it would be to kill one and prove their existence because few people had seen one. For the first time a mermaid had been seen on their ship and had been captured. Barty was about to make his dream come true, but he didn't expect this mermaid to look like... that.
