A grotesque, melancholic meditation on grief and artistic obsession, where a dying mermaid becomes both muse and mirror for a broken man's despair.

An artist dealing with the grief of his wife leaving him finds solace in painting the squalor of the sewer. He discovers a trapped mermaid, whom he brings home to heal. Her condition worsens, and she asks the artist to paint her before she dies.
