Trapped in a car wreck, upside down, bleeding and in pain, Tristan and Grace are staring at death. When dawn breaks they might be seen from the road and rescued, or not. They wait desperately holding onto life, unravelling the sequence of events that brought them together. Tristan is a philosopher struggling with the question of free will. Grace's life of hardship allows no place for such ideas. But a brief encounter changes their lives, setting them on a collision course with love and death - and each other.
