The show chronicles the lives of the Harpers, a fictional middle-class British family who live at 78 Lancaster Road, Chiswick, London. Dentist Ben and his wife Susan, a tour guide who later works for an art gallery, have three children: Nick, Janey, and Michael, who endanger their lives. Susan is a control freak, but Ben prefers to leave the children to it and stay as uninvolved as possible. Janey later goes to University, but drops out and moves back in later, while Nick finally gets his own place.
