Diana falls and breaks her hip whilst throwing a brick at the home's incompetent South American gardener. She is taken to hospital where she rows with the Welsh doctor over a hip replacement operation and Sarah, about to marry Sam, comes to visit. Sarah knows that Diana dislikes Sam and wonders if she will try to stop the wedding..or even attend.
In the end Diana turns up for her niece's big day, using a Zimmer frame.
Marion, meanwhile, is not making a success of the beauty shop and Tom suggests Sam take back the franchise.
