As the effects of the war raging in Europe begin to be felt at home in London, Monica Dickens decides to do her bit and to pursue a new career, and so enrols as a student nurse at a hospital in rural Hertfordshire. By nature clever and spirited, she struggles to submit to the iron rule of the Matron and Sisters, and is alternately infuriated and charmed by her patients. That's not to mention the mountains of menial work that are a trainee's lot. But there are friends among the staff and patients, night-time escapades to dances with dashing army men, and her secret writing project to keep her going.
