Eight men and two women trapped high on a mountain, a killer fog below wiping out every living thing in its path. Is it the end of the world or just the beginning? Sexual norms are thrown out the window by the two beautiful girls, realizing that they must share their sexuality with all in order for the species to survive. From the secret dungeon room in one of the houses, outfitted for those with the most jaded tastes to a menage a trois, they navigate the deep, dark hidden desires in each of them. Some of them succumb to these desires; others turn it to their advantage. Will their sexual survival be enough to save the species? Or will they be degraded into sexual puppets to be manipulated by the strongest?
