Geraldine forms a book club at which Alice deciphers the Da Vinci Code and works out that she is the last living descendant of Jesus Christ. Geraldine,however,is depressed. She has conducted a hundred weddings but is still single herself. An attractive young couple arrive to take up a weekend cottage - Harry and Rosie Kennedy. Geraldine is smitten by Harry and is relieved to find that Rosie is his sister,not his wife. They begin dating.
Geraldine turns down Owen's final pleas to marry him and the villagers' suggestion that she should have a sky-diving wedding,to get married to Harry. Alice is charged with being the wedding planner and she chooses a Doctor Who theme.After the Reverend Jeremy Ogilvy has conducted the ceremony and a montage of scenes from Geraldine's life has been shown Alice finally understands the vicar's closing joke,thanks to Harry.
Geraldine and Harry agree to a wife-swap,as in the TV show. He goes to live with Trudie Styler for a week while her husband Sting moves in with Geraldine. Alice warns him off the vicar using Police song titles and Geraldine gets him to do the housework in the nude. On the last day he tells her that if her marriage ends she should come and live with him -but only as his cook. Then Trudie comes in,having got a little too flirtatious with Harry. Mr. and Mrs. Sting both end up with a cake in the face,thanks to the vicar.
