Matthew dangles at the end of a rope, broken, in a dim spot of moonlight, calling to his unseen climbing buddy Harvey.  He suddenly falls out of the moonlight, his rope trailing after him.  Days later Harvey breaks camp, haunted, knowing that to save his own life he had cut the rope holding Matthew.  Weeks later Harvey visits Matthew in the hospital—he miraculously survived the accident that he, in fact, had caused.  Harvey reverses roles, six stories above the ground, and gives Matthew a chance to cut the rope to save his own life at the expense of Harvey’s.
