The daily lives of the men and women at Sun Hill Police Station as they fight crime on the streets of London. From bomb threats to armed robbery and drug raids to the routine demands of policing this ground-breaking series focuses as much on crime as it does on the personal lives of its characters.

Based on the acclaimed novel by Doris Lessing, this dystopian science fiction tale concerns a woman struggling to make her way in a post-apocalyptic society. D (Julie Christie) is living in a city that's at the point of collapse following a catastrophic nuclear war; lawlessness and violence rule the day, and gangs of brutal youth roam the streets. With the help of her teenage companion Emily (Leonie Mellinger), D tries to make her way, and in order to cope, she often escapes into a fantasy world in which she lives in genteel Victorian surroundings in the 19th century.
