On the 26th of October 2002, while participating in an elaborate treasure hunt known only as “The Game”, software engineer Bob Lord entered an abandoned mine shaft in the desert near Las Vegas. He was convinced that he was on the right track to retrieve the next clue in the 24-hour marathon hunt. He was wrong. In the pitch blackness Bob slipped and fell to the bottom of an unseen shaft, sustaining injuries that would change his life forever.
