After having his career scrutinised by the General Medical Council because of his blood phobia, Martin makes efforts to overcome his fear and begins to question whether he made the right decision about resigning.

The surgery is chaotic, with both Martin and Louisa now practising from it. Bert's new business venture with Al doesn't get off to a good start, and Penhale suspects noise complaints are due to paranormal activity.

Martin is called to an emergency at a local farm, but much to his annoyance the sick farmer, Ron Pickford seems well enough to be managing his lambing sheep.

Martin rubs up against the new herbalist and Penhale, Louisa and James are all interested in Janice's new pedicure fish. Martin's ex-flame invites him to speak as keynote speaker at Imperial College, and Ruth is back from Mexico with more than maracas.

Louisa is shocked and Martin suspicious by the unannounced return of her father. Ruth is helping Martin with his blood phobia when she discovers his predicament, and an unexpected caravan squatter thwarts Bert's dreams of making a quick buck.

The news of Martin's Imperial College job offer is flying through the village, but the Ellinghams are yet to make a decision. Caitlin blames Bert for the flooded pub cellar, and an emergency on the rocks helps Morwenna make some important decisions.

The villagers throw the Ellinghams a farewell party and Ruth helps Mrs Tishell deal with the news and encourages her to attend, but it seems that Martin and Louisa aren't going to make it because a farmer has spotted their lost dog.
