Sharon visits Tracey's luxury house, 'Dalentrace', in Chigwell and meets Dorien for the first time. Meanwhile, their husbands, Chris and Darryl, take part in an armed robbery and are later jailed for twelve years. Sharon moves from her high-rise Edmonton flat to stay at Dalentrace with her sister.

Sharon's day hasn't started well. She accidentally breaks a mug and spills coffee everywhere and then Tracey accuses her of not paying her way. Tracey is having problems with money, so she and Dorien try to sell some clothes. Meanwhile, Sharon has to go back to her job at the supermarket, but she isn't feeling welcome.

Sharon goes to the aid of 53-year-old Don Sheridan who is mugged at Chigwell tube station. That evening, they accidentally meet at a bar and he says he is in Chigwell on business as financial adviser to Marcus, who is apparently near to going under. They go out several times and sleep together, despite him being married. On his final night before going home, they plan to re-live the 1960s by taking drugs, which Sharon had been given to pass to Chris in prison. The police arrive to return Don's wallet, leading Don to flush the drugs down the toilet. Meanwhile, Dorien pays £2000 to have her telephone number changed to 071, as she sees it as more exclusive.

As Sharon approaches her 30th birthday, she looks back on her life and regrets her lack of education. She pays a visit to her Edmonton council flat, where she meets Lisa, whose criminal partner is in the property business and Sharon considers buying the flat. Tracey disapproves of the idea. Dorien, however, is more encouraging and goes with Sharon to the flat. However, Lisa's partner is soon sent to prison and Sharon then takes his place on a holiday with Lisa to Benidorm with Club 18-30.
