Todas las criaturas grandes y pequeñas

James Herriot is a vet in Yorkshire, England, during the late 1930s and 1940's. He gets a job at the practice of Siegfried Farnon, who (together with his mischievous brother Tristan) already have a successful business. James undergoes a variety of adventures during his work, which are just as often caused by the characters of the county (including the Farnon brothers) as the animals in his care.
