Rita tries to talk her round but she is adamant she's not right for Derek. Rita and Alf go to the church to tell Derek only to find he's not there either. His best man, Carl Stanton, tells them that Derek can't go through with the wedding. Whilst Rita starts rowing with Edith Wilton over who jilted who, Alf has to break the news to Reverend Unsworth.
