Revolves around married English couple named Bob and Margaret Fish, a middle class 40-ish working couple with no children and two dogs named William and Elizabeth. Bob is a dentist and Margaret is a chiropodist. Bob and Margaret struggle with everyday issues and mid life crisis. Stories often revolve around the mundane, but in a way which is eminently relatable. In the first two seasons, Bob and Margaret live in England, in the South London community of Balham. For the third and fourth seasons, they move to Toronto, Canada, allowing the writers to explore the humour of the culture clash.
