I just can't see myself in anything other than black and gold Ben

In 1976, David is fishing off the island of Black Conch when he comes upon a creature he doesn’t expect: a mermaid by the name of Aycayia. Once a beautiful young woman, she was cursed by jealous wives to live in this form for the rest of her days. But after the mermaid is caught by American tourists, David rescues and hides her away in his home, finding that, once out of the water, she begins to transform back into a woman.
