It is 1935. Robert Owen is the only son from a Welsh vicarage, now a brilliant pilot and flying instructor, recently of the Royal Air Force. He has taken a new job at the flying school at Best, a prosperous cathedral town in England. Flying has never seemed so alluring and so terrifying. Human frailty is tested in the drilling and repetition of hours in flight, and Robert's skills as a pilot and in diplomacy with pupils with delusions about their competence are tested to their limits. And then he falls in love, risking his heart as well as his body in the air.
