The film will tell the true story of the relationship between Welsh schoolmaster Philip Burton and a wild young schoolboy called Richard Jenkins. Richard dreamed of becoming an actor, but his ambitions were in danger of being derailed by a combination of family trouble, the pressure of war, and his own lack of discipline. Mr Burton recognised the raw talent in his pupil, and made it his mission to fight for him, becoming his tutor, strict taskmaster and eventually his adoptive father.
