There's no retiring our Gay is there? Not that we're complaining, the broadcaster is well able for it after all. This doc will follow Byrne as he learns about his father Edward's experiences as a member of the cavalry in the British Army during the First World War. His father thankfully returned from battle, but not without his war wounds and would often suffer from terrible nightmares in the aftermath. This year marks the centenary of the conflict, and Gay will talk to leading historians and military experts as he embarks on a personal journey of discovery to learn the full story of his father's time on the front lines.
