The series was a period drama created by Julia Smith and Tony Holland (who both went on to create EastEnders) and starred Nerys Hughes as Megan Roberts, the titular district nurse fighting to improve living conditions for the people living in a poverty stricken mining town, Pencwm, in South Wales during the late 1920s.
In the third series, shown in 1987 and set in the early 1930s, Megan had moved on to the seaside town of Glanmor where she worked with a father/son pair of doctors - Emlyn Isaacs (Freddie Jones) and James Isaacs (Nicholas Jones).
