Surrounded by new 1950s East End high-rise flats, a London detective thinks back to how different things were in the late 1930s. Then it was an area of overcrowded tenements teeming with impoverished unemployed people with little or no hope. He relates the story of attractive young Hetty who desperately tried to stop her younger brother descending into crime while her mother was endlessly urging her to take up with Wilkie, a smooth local racketeer, in the belief this would get the family out of poverty.
