A man in a silk top hat stands in front of an empty aquarium. He pours water into his hat and goes fishing, hooking a small one. He becomes a hobo and catches more and more fish from the hat. Then he starts pulling out rabbits. The backdrop becomes the sea, and a mermaid appears. She flirts and beguiles us. The mermaid becomes a woman who leaves the sea and joins the magician, who becomes Neptune.
