Sarah Williams travels back to her childhood home for her father's wedding, but her return threatens to dig up long-buried secrets concerning her sister's husband.

Sarah prepares for her first day at work but is made to feel unwelcome by her manager, Deborah. Nevertheless, she rolls up her sleeves and gets to work on a Border collie.

George waits for his passport to arrive so he can go on a honeymoon; Claudie makes her presence felt in the household, infuriating her stepchildren in the process; chaos erupts on the day of Imogen's christening.

Tom is sleepless after helping a cow give birth and a lack of rest leads to him mistakenly castrating a prize stud dog. His worries are compounded when Anna becomes angry about his secretive behaviour.

Claudie's past catches up with her when Matt finds out someone is drawing money from his dead grandmother's pension. An investigator informs him the money has been paid into an account in Malta.

Margaret saves the practice from a PR disaster on the day of its relaunch. However, the staff are surprised to see that the business' new sign doesn't bear George's name.
