Martin Clunes stars as Dr. Martin Ellingham, a doctor with a humorously brusque bedside manner and a phobia of blood. He finds himself back home in a Cornish village after his illustrious medical career in London goes awry. The townspeople are not used to the doctor’s blunt opinions and insensitive manners, often leading to mayhem in the town of Portwenn. Caroline Catz plays schoolteacher Louisa Glasson, for whom Doc Martin finds it difficult to express his romantic feelings.
