Plot
The series follows the plight of Ra'Nell as he navigates the pitfalls of living on the crime-filled Summerhouse estate after his mother, Lisa, is admitted to a mental hospital. Ra'Nell, who has gained a reputation around the estate for his volatile behaviour after stabbing his abusive father, is quiet and closed-off. While his mother is in hospital, he is cared for by her close friend, Leon, who was once a respected enforcer of the estate, but has since put his past behind him. Meanwhile, Lisa's friend Heather enlists Ra'Nell's help to grow a cannabis crop so she can earn enough money to move out of the estate and raise her unborn child somewhere safer.

Meanwhile, his best friend, Gem, finds himself in over his head when he begins to work as a drug dealer for Summerhouse kingpins, Dushane and Sully. Gem is easily coerced and finds himself at the mercy of their trusted enforcer, Dris, who is ruthless and violent.

Dushane and Sully run the estate together with relative ease, but when Kamale, a rival drug dealer from London Fields steals a large amount of their supply, they are forced to hunt down the thief before their supplier, Bobby Raikes, takes action. The urgency of the chase puts Dushane and Sully's partnership in jeopardy.
