Doc Martin stars Martin Clunes as the brash “Doc” Martin Ellingham who 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 school teacher Louisa Glasson for whom Doc Martin finds it difficult to express his romantic feelings. Think you know everything about Doc Martin?
