On the night of the blue moon James Morgan pulls up something fantastical in his fishing nets. Kind, simple and strong, the seaman has pined for a mermaid since hearing the legend when he was a child. Haunted by all he's lost, and challenged by a photographer's quest to capture the legend on film, he also struggles between greed and doing the right thing. But what the sea gives, the sea takes away. Is it possible for a man who walks the earth to love a woman who is fated to swim the sea?
