Billy Hill and Jack 'Spot' Comer were among the most notorious criminals in London up until the 1950s. Dramatising the violent reign of two of London's most notorious gangsters, Billy Hill (Leo Gregory) and Jack 'Spot' Comer (Terry Stone), ONCE UPON A TIME IN LONDON charts the legendary rise and fall of a nationwide criminal empire that lasted until the mid-fifties and which paved the way for the notorious Kray Twins and The Richardsons. This is the story of their rise and fall.

In 2004, a Home Office survey revealed that there are 20 to 60 youngsters,aged 16 to 24,living rough in each inner city in the UK. They are responsible for vast levels of crime and in almost all cases they have come from broken homes and a history of abuse,both physical and sexual,most of the time inflicted on them by their own parents. Nikki,18,fled a sexually abusive homelife and a succession of foster families to live on the street. There she met Vincent,21,the product of heroin addicted parents. Together they spend their days trying to survive the perils of living rough and supporting their own drug addictions. They are wild,unwanted and trying to live without fear.They are the lost children of modern day society. They are The Feral Generation.
