That story I started last post Part Deux

The pair of adventure-crazed adrenaline junkies followed the barge to a port on the coast of Antarctica. The barge was unloading large crates by the time they caught up to it. In the distance they could see that their presence was finally noticed. Men could be seen pointing in their direction, then hurrying off in different directions. "It's about time." says John Finch. "We've been behind them for two damn days" He then stands high up on the bow and waves. His greeting is returned, with cannon fire.
   The sailboat doesn't stand a chance. The sea swallows it, and the Finches. The secret remains safe. If it got out, millions would be slaughtered in the ensuing chaos. It was a necessary loss. Small craft are sent out to make sure there were no survivors. Teams begin to seek out the ship and who sent it. No one must ever know what is housed here. Anyone possessing even the slightest knowledge of this place or it's contents must be eliminated. No exceptions. It is crucial to the survival of the entire human race.
   After an indeterminable amount of time Kait Finch wakes on an icy embankment. Her body is numb with cold. She finds John and wakes him. They're delirious and lost. All around them a blanket of white obscures the landscape. Out of a mad desire to survive even this, the couple wander stumbling through the cold, determined to find anything, to live just a bit longer if anything. They find a cave in the side of a cliff. They crawl inside and rest their aching legs. They sit together knowing death is not far off. They exchange words of love and of having not one single regret. They lived according to their principles 100%.
    Just as it seems all hope is lost, they hear strange noises emanating from deep inside the cave. "You up for one last adventure, Honey?" asks Kait. "You know it." laughs John. Struggling with effort, the couple rise to their feet and make their way deeper inside the cave. The temperature rises consistently as they travel. Eventually, they strip off most of their heavy frozen clothes. They come across some stalactites dripping water and stand under them mouths open. Some of their strength returns with the meager hydration.
    They continue deeper into the bizarre cave. John notices a light at the end of one tunnel. He and his wife can't believe their eyes. Reaching the aperture, the cave opens up revealing a lush jungle. The Finch's fall to their knees in disbelief. Kait is the first back to her feet. The only thing she can think to say is,  "I've seen just about everything, but what the fuck is this?"
