Alison Braithwaite's lottery win is no longer a secret and the family have left the suburbs behind to live in a mansion in the country.

Alison has decided to call off the divorce. The girls organise a surprise second honeymoon in the Lake District for their parents but David had been planning his own surprise trip to New York.

It's Charlotte's birthday and David has forgotten. It seems like Alison and David's marriage is, once again, over. David's brother Graham turns up and his marriage is in trouble too. Will Alison go out for dinner with him?

The Braithwaites appear to have split up for good and Sarah and Baby William move in with David. Charlotte tries to help bring the family back together by signing them up for a TV quiz show, 'Family Challenge'.

Alison has fallen in love with Graham. David has hired a private detective to follow his wife and is devastated when he finds his worst fears have come true. Feeling desperate he confronts her and asks if they can get back together.

Graham now has his feet under the table at the mansion much to Charlotte's disgust. Due to her unhappiness she disappears on her first day at a new school causing much worry for Alison and David.

Charlotte summons David and her sisters out to the moors where she has lured Graham down a mine. Once Graham is rescued, David's resentment of his brother leads to the two of them having a fight.

Alison is struggling to deal with the news that David thinks he has murdered Graham when Tamsin phones to tell her that Virginia has fallen into a river. Fearing a suicide attempt Alison and David rush to their daughter's bedside in hospital.
