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.
Portwenn is abuzz with activity for the preparation of Janice and Penhale's wedding, but a medical issue could prevent Penhale from making it down the aisle. Meanwhile, Al is struggling with the demands of being best man, especially when Bert's marketing antics mean there is only whisky available at the pre-wedding party.
Martin and Louisa search for a nursery now that Janice has left, and Mrs Tishell is shocked to find out that Al has very high blood pressure. Louisa also helps with the diagnosis of a pupil, which spurs her on to explore the possibilities of a change of career. This is not welcome news for Martin, who dislikes any kind of change, even if it could be for the better. Elsewhere, Ruth is approached about selling her farm. Starring Martin Clunes, Caroline Catz, Selina Cadell and Ian McNeice.
