Wedding bells are ringing for the Doc and Louisa. But will the marriage finally go ahead?

It is Louisa's first day back at school and their new child minder, Mel, is late for work. When Mel finally does arrive Martin is dubious about handing James over to this woman who is constantly scratching.

A stranger stops dead in his tracks when he sees Ruth in the village, and later he spies on her when she is having a coffee with Caroline. Ruth is not sure why, but she starts feeling uneasy.

Louisa wants Martin to engage more with James, so she arranges for him to take their baby to playgroup, where he has to pair up with a mother and daughter and sing songs.

Mrs Tishell returns to the village. Martin has to work out what is wrong with beach comber Lorna. Al and Morwenna have an internet dating disaster, and romance is blossoming for Bert and Jennifer.

Hypochondriac Malcolm Rayner is struggling with his breathing and Martin asks him if he has ever worked with asbestos.

Al receives a visit from two military policemen who are trying to track down Baby James's babysitter, Mike Pruddy.

Louisa is leaving for Spain, Bert and Jennifer's engagement party goes off with a bang, and Al is hailed as a hero for saving Caroline's life.
