To Serve Them All My Days (1980)

"The BBC's classic story of an English schoolmaster's life of tragedy and triumph between the wars"

After barely surviving the trenches of World War I, an embittered young soldier takes a teaching post at Bamfylde, an elite boarding school in the uplands of West Devon. It is an unlikely job for a Welsh miner's son without a degree, but David Powlett-Jones (John Duttine) proves to be a rare schoolmaster, as passionate about learning as he is about teaching. Through two tumultuous decades, Powlett-Jones inspires his students with his courage and idealism, qualities that help prepare him to send another generation of young men off to fight yet another war.
