New neighbours look set to disturb the tranquillity of Portwenn, upsetting the locals with their unconventional lifestyle and even managing to gatecrash an intimate dinner between Martin and Louisa. Meanwhile, a car vandal strikes the village - but agoraphobic village copper PC Penhale is too scared to leave the station and investigate.

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.
