Martin and Louisa are about to get married but will it ever happen. Martin is feeling irritated by PC Penhale, who wrongly believes that he is going to be the best man and Louisa is also late for the service. The vicar has serious doubts as to whether she will turn up, leaving Martin on edge. After she finally arrives the couple are married. Things after the wedding don't go as Martin hoped and Ruth has a difficult time looking after James.

The GP is left holding the baby after upsetting the new childminder, but luckily Mike agrees to look after James at short notice. However, Louisa is not happy with the arrangement and an argument erupts between the newlyweds just as their guests arrive for dinner - and that's only the first of the evening's problems.

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. One of Louisa's pupils blames an upset stomach on a meal she ate at Bert's restaurant and writes about it in the school magazine. Bert and Al are furious, and they go to see Louisa wanting something to be done.

When Martin is talked into taking baby James to playgroup, he is forced to sing along with the other mums. As the parents pair up, one of them says she is worried about her daughter, to which Martin replies that the girl is probably just backward. Al helps Ruth move into a cottage in the village where she meets her new neighbour, a grumpy old man called Moysey. When Moysey goes for a repeat prescription for his asthma, Martin notices that his breathing has got worse - but he takes exception to being poked and prodded. Al admits he would like a girlfriend and asks Morwenna if she has any single friends. Morwenna asks her mate Janice, who is not impressed by the idea. So a desperate Al decides to sign up with Cornish Couples, a dating website.

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.

During an examination, Mrs Tishell is smitten by Martin holding her hands and staring into her eyes, and falls head-over-heels in love with him again. Two military policemen call at the police station looking for Mike Pruddy. Al pretends not to know Mike, then goes to warn him the army are looking for him. Louisa has shocking news for Martin.

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.
