A thrilling and raw crime drama following a gang of drug dealers in Hackney, London - an honest and gripping rendition of inner-city drug and gang culture.
In the courtyards of the Summerhouse Estate, a thriving but underground drugs business is being run by Dushane and his friend Sully.
Raikes gives Sully and Dushane two weeks to retrieve the stash stolen by rival Kamale and they find a mysterious present of guns to help them.
After Heather has shown him the flat she hopes to buy with her drug money, Ra'Nell welcomes his mother home. Sully visits his daughter.
Dushane is shocked that Sully still has the gun that killed three people but refuses to go along with Raikes's plan to sell him out as a liability.
Under the wing of his boss, "Top Boy" Dushane faces a new rival: his one-time friend Sully. Meanwhile, Ra'Nell's mother tries to rebuild her life.
While visiting the injured Joe, Dushane discovers who stole their drugs. Meanwhile, Mike and Sully botch a hit, and police descend on Summerhouse.
Sully asks for a sit-down with Dushane, and Rafe swears vengeance on Sully and Mike, who abducted his younger brother, Jermaine.
Gem's father retaliates against Vincent for beating Ra'Nell, and Dushane and Sully reunite to retrieve the stolen drugs from the Albanians.
