Rough seas founder the steamship "Placation" off the coast of a mysterious island. Surrounded by hundreds of miles of icy water and howling winds, the secluded land has never been seen by mortal eyes. A sailor narrowly survives the sinking thanks to the efforts of the towering Mistress also trapped on the isolated rock. Now he is completely at her mercy, owing his life to a mare with impure intentions.

If he wishes to stay on her island and avoid the icy depths, her demands must be met.
