It's episode two of this Sebastian Faulks adaptation. As Stephen recovers from his injuries, he is still haunted by memories of his affair with Isabelle. While he and his men prepare for a major offensive at The Somme, Stephen unexpectedly meets Isabelle again, but she is unable to explain why she left him, and Stephen goes into the attack in a state of turmoil, not sure whether or not he will see her again. The battle is devastating. Over the months that follow, Stephen begins to find comfort in his friendship with Jack Firebrace, and when Isabelle's sister Jeanne reveals the secret which Isabelle had hidden from him, Stephen starts to believe, at last, that there is a future worth fighting for.
