Two seasoned drug dealers return to the gritty street of London, but their pursuit of money and power is threatened by a young and ruthless hustler. This drama takes viewers into the housing estates of east London. There is tension between the drug gangs that operate almost openly and those who strive to live honest lives against the odds in the crime-riddled area. That tension is explored through the interlocking stories of 20-something drug dealer Dushane, who is determined to become the area's Top Boy, and good-natured but vulnerable teenager Ra'Nell.
