In the near future, a woman writes from the depths of a forest. Her body, like the world around her, is falling apart - she's down to one eye, one kidney, one lung. Before she was a psychotherapist, treating patients who had suffered trauma. Every two weeks she visited her 'half' ' a comatose double, whose body parts were available whenever needed. As a form of resistance the woman flees, along with other fugitives and their halves. But life in the forest is disturbing too - the reanimated halves behave like uninhibited adolescents, and when she sees a shocking image of herself on video, are her worst fears confirmed?
