The irascible medic and Louisa embark on what seems to be a perfect first date at a classical music performance in the grounds of a country house, but an inappropriate remark from the doctor kills off any chance of romance. Elsewhere, Al worries that Pauline's gambling is getting out of hand when he finds out that her moped has been repossessed.

The doctor and Louisa make plans for their wedding, but the big day runs far from smoothly, as a drunken vicar leaves Martin with a dilemma. Meanwhile, the restaurant where the reception is to be held is flooded and Isobel goes into labour.
