The drama will shine a light on James's early friendships, his inspirational relationships with adults, his rocky quest for knowledge, and see his compassion for animals and principled humanity put to the test, in ironic, tragic and sheer comic episodes of animal - human relationships.
Airing on BBC One, the series stars Glasgow actor Iain de Caestecker as James Herriot, with Amy Manson as Whirly Tyson and Ben Lloyd-Hughes as Rob McAloon.
