Jamie Daniel begins his rise from the tough streets of Possil in north Glasgow - first as a scrap metal dealer and then as a major player in the city's flourishing drug trade.
One of ten children, Jamie followed his brothers into the family scrap metal business. But as heroin took hold in the city, he spotted a business opportunity that would catapult him into the big league - importing large quanitities of the drug into the country.
The city's underworld was changing too. From the razor wielding street gangs of the 1930s to the postcode turf wars, drugs would mark a step change in the criminal landscape. But as business boomed for Jamie, danger was on the horizon.
