Birds of a Feather (1989)

Season 2: Episode 7

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.
