Then Barbara gets it into her head that cheery new neighbours Angela and Norman are stealing her Christmas tree and poinsettia and her efforts to retrieve them lead to friction with Ted. Martin and Linda turn up as Martin's surfeit of Christmas lights has blown all the fuses in the house and left them in the dark. Thus there are two quarrelling couples spending Christmas under the same roof.
