A golden-tailed mermaid secretly visits a sealed, ancient black-tailed merman, driven by a desperate plan to conceive a golden egg with him in three days to become Sea Queen and avenge her past life. Her companion warns her of his violent, ancient nature and the danger of his two 'sea god tentacles.' Undeterred, she takes hallucination and conception gels to force the encounter. Finding him, she drugs him during an early 'tidal heat,' but he awakens, fully aware of her trespass and deception.
