Final Ascent follows his determination to regain his freedom, reclaim his past and reconnect with old friends like Michael Palin. Triggering lost memories has required him to watch his own documentaries, read his books and reconsider his achievements. The viewer shares every step of his remarkable journey in this gripping and poignant documentary.
