Alan Bauer nearly drowned as a child but has memories of being saved by a young mermaid. When he is jilted as an adult and loses his wallet in the surf, the young mermaid tries to return it. They are soulmates who have been meant for each other, but Madison fears how he will react when he finds out she is not human.
