The GP is left holding the baby after upsetting the new childminder, but luckily Mike agrees to look after James at short notice. However, Louisa is not happy with the arrangement and an argument erupts between the newlyweds just as their guests arrive for dinner - and that's only the first of the evening's problems.
Make an appointment with the brilliant but socially awkward and neurotic Doc Martin. When Martin develops an aversion to blood, he abandons his career as a celebrated London surgeon and becomes the only doctor in a sleepy small town where his tactless manner soon has the whole town in an uproar.
