In the depths of the ocean, the ancient fish god Dagon rises from his underwater palace, not in search of food but in search of a mate. Dagon is on a quest to find himself a bride. Barely breaching the watery surface, he spots a gorgeous girl on a boat hanging out with her friends on a bright sunny afternoon. He cannot tear his eyes away from her.

Upon seeing her, He immediately becomes infatuated with her and it is then he decides that this girl will become Dagon's Bride. The girl he chooses, eighteen year old Felice Caldwell, has a deathly fear of the ocean and the creatures that inhabit it. So how will she handle it when Dagon has her transformed into a mermaid to become his bride and Queen of the sea and live with him for all eternity?

Once Felice is transformed and now living in the ocean, she is frightened by the series of events that have occurred. Dagon proposes to her with an elaborate aquatic ring fit for a Queen and Felice reluctantly accepts. Dagon introduces Felice to numerous aquatic creatures that she knew from mythology and others are entirely different breeds that have been around for eons.

Being in the ocean, Felice feels a mixture of emotions. First, she feels fear that she will be wed to the grotesque fish god and be surrounded by hideous aquatic mutations except for the mermaids, who are all anxiously awaiting to meet her upon her arrival beneath the sea. Second, she feels somewhat delight at seeing things that human eyes are not allowed to see, but that is only a small part of her. Felice very desperately wants to become human again, but Dagon wants to keep her in the ocean for the rest of her existence. Will she make it out?
