Bernard Newton is leading the surgery, which puts Martin at ease given he was his tutor, colleague and old friend.

Wedding bells are ringing in Portwenn with the preparations for Morwenna (Jessica Ransom) and Al's( Joe Absolom) wedding. But some last minute hitches threaten to jeopardise their big day.

There's an awkward meeting for PC Penhale (John Marquez) when his ex fiancé Janice Bone, (Robyn Addison) returns for the wedding. She left him standing at the altar, and he now wonders if she's back because she still has feelings for him.

While at the surgery Angela comments on Buddy, the dog, not being himself. Buddy's condition worsens and Martin rushes him to Angela's surgery. He discovers Angela can barely see and diagnoses cat scratch fever. But her condition means she can't operate on Buddy, and that the Doc must carry out the surgery himself, under her guidance, to save the dog.

Martin and Louisa have their first fertility consultation with Dr Emma Ryder. Well aware that Martin is able to perform the tests himself, she reminds him that he is the patient now, not the doctor.

Martin investigates after local farmer Dennis Thorpe shoots at Robert for taking some of his eggs. Meanwhile, Emily returns to the surgery to see Martin after her acne medication caused a bad reaction, a secret bidder buys the Crab and Lobster pub, and Louisa ponders if she should see a fertility specialist.

This time, Martin has his second GMC assessment - mock surgery - and Buddy is missing. Meanwhile, Ken's arrival does not bring good news for Al and Bert, and Penhale unhappy with the arrival of his predecessor, Mark Mylow, who tries to take charge of his investigation.

Ruth is concerned about becoming increasingly forgetful, and is even more perturbed when Martin offers to perform a mini mental state examination. It confirms she is showing early signs of dementia. Meanwhile, Louisa plans a special evening to celebrate Martin's birthday, and Al decides to throw Morwenna a surprise engagement party on the same night. There are also problems when Louisa's class tutorial ends in disaster.

Dr Martin Ellingham's GMC report has arrived. He's required to pass three refresher courses, which will then decide whether he is deemed fit to practice, starting with a phlebotomy course.

Martin's medical career remains under scrutiny, as a GMC representative has come to assess him and his surgery. Meanwhile, Al accidentally proposes to Morwenna, and Mrs Tishell has a new lease on life.
