The Mechanical Tears Of The Immortal Being

A famous author is invited to a party in the middle of nowhere, a party attended by some of the most powerful people in the world. On the way there, he meets a porn star. Later, when they're already at the party, he watches as the poor woman is taken away because some people want to have fun with her. And why was he invited to that party?
Years later, that same writer takes a private flight to New Zealand. One of the passengers on that flight is the billionaire Samuel Obberbrunner. Unknown to everyone, Samuel is heading to his bunker where immortality is waiting for him. But to achieve immortality he will have to leave love and everything else behind him for a long time.
