David Powlett-Jones has just returned to England from the trenches of WWI. He was injured and shell-shocked and, after a spell in hospital he gets a job teaching in a boys boarding school in S.W. England. He is not at all sure he can do the job, but the avuncular headmaster has faith in him. David, although well educated, is just a humble lad from the Welsh valleys at heart and has to fit himself and his ideas into the heart of the English establishment.
