Dead Man Walking follows two opposing narratives. The first is Nathan Carter, whose younger brother recently committed suicide. Convinced that foul play was involved in Connor's death, Nathan sets out to understand what really happened to him. The second narrative, that begins nine months later and over 200 miles away, follows James Saxby, a fishing boat deckhand who is keeping secrets from his fiancee. But what will bring these two narratives together, and what does James know about the day Connor Carter died?
