In the 1930s, fresh from a stint in the Royal Navy Reserve, and against the wishes of his disapproving father, Fingal O’Reilly goes to Dublin to study medicine. Fingal and his fellow aspiring doctors face the arduous demands of Trinity College and Sir Patrick Dun’s Hospital. The hours are long and the cases challenging, but Fingal manages to find time to box and play rugby—and to romance a fetching, gray-eyed nurse named Kitty O’Hallorhan. Dublin is a city of slums and tenements, where brutal poverty breeds diseases that the limited medical knowledge of the time is often ill-equipped to handle. His teachers warn Fingal not to become too attached to his patients, but can he truly harden himself to the suffering he sees all around him—or can he find a way to care for his patients without breaking his heart?
