As chair of the residents' association Hester opposes the demolition of an empty building to make way for flats, proposing that it become an retirement home instead. To prove the need for one, she persuades Guy, Nancy, and Nancy's sister Winnie to pose as helpless, deluded old folk when Mr. Gardner, head of the council. visits. Not only is he so convinced that Hester's plan goes ahead, but he's so concerned about the old folk that he arranges for them to be moved to a care home ASAP.
