Martin makes his debut on a local radio station - but doesn't make a great impression on the interviewer, Bert and Al argue over Al's plans to go to college, and a nasty stomach bug sweeps through the village - but is the swimming pool or the water to blame? Meanwhile, Louise is keen to make amends with Martin, but then Mark invites himself along too.

The Doctor comes face to face with Danny, an old flame of Louisa's who has returned to the village to visit his ageing mother, but the two fail to get along. Plus, is there a mugger in the village?

The preparations for Martin's departure are nearly complete, and he is surprised by the number of patients coming to see him on the last day before his surgery closes. Edith visits to say she will see him in London. Taxi driver Tommy is complaining of migraines, but Martin does not realise the significance until Tommy's wife Tasha collapses with the same symptoms during the Harbour Day celebrations.

Portwenn looks set to become a hotbed of passion. Louisa Glassons is furious to discover she has a rival for Dr Martin Ellingham's affections: glamorous divorcee and hotel owner, Carrie Wilson. Can Louisa contain her jealously and claim Martin as her man before Carrie's flirty tactics take effect?

Since Martin and Louisa both got cold feet on their wedding day, Louisa has left, and Martin has been finding life in Portwenn infuriating. When he unexpectedly meets his old flame Edith, now a top-ranking doctor who is clearly surprised at the way his life has turned out, he starts to consider new directions, but Martin's thoughts are turned upside down when Louisa returns - with big news of her own.
