Young people living on the edge and, for the most part, living out of sight in East London today based around inner-city drug and gang culture.

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. To remind them of their responsibilties Raikes' henchman Greene attacks Dushane's brother Chris and gets badly beaten up in revenge. The boys decide to kidnap Kamale's cousin Shaun and hold him to ransom but they hit him just that little bit too hard and end up with a corpse on their hands. Meanwhile Ra'Nell misses seeing his mother on her day out from hospital as he is helping Heather tend her illegal crops and Gem loses his cherry in as disused warehouse.

After Heather has shown him the flat she hopes to buy with her drugs money Ra'Nell welcomes his mother home. Sully visits his daughter but Chris bars Dushane from his house as a liability. Sully suggests to Dushane that an informant in their group is in league with The London Fields. He names Gem and sends a thug,Dris,to kill the boy's dog and send him into hiding before Ra'Nell gets the courageous Leon to call the gang off. Though Kamale does not turn up to Shaun's funeral a chance sighting leads Dushane and his gang to their rival where,after claiming another victim,they locate the missing drugs at a tyre depot,where Lee Greene just happens to be so they shoot him too but now a full-scale gang war erupts as Kamale's associates seek revenge.

Dushane is shocked that Sully still has the gun which killed three people but he refuses to go along with Raikes' plan to sell him out as a liability. Overhearing Vincent,Heather's Vietnamese buyer,refusing to give her the price she wants for her weed,Ra'Nell persuades Dushane to pay the required rate and shows him a sample of its quality. Heather goes to hospital and gives birth,admitting to Lisa how she involved Ra'Nell in her scheme. Lisa rings Leon,who tries to prevent Sully from stealing the marijuana from Ra'Nell but in the fight that follows Sully shoots and kills Leon.Dushane visits Raikes on the pretext of giving Sully up but shoots him and makes it look like suicide. He gives Ra'Nell the money for the weed,which he passes on to Heather and,as Ra'Nell,Gem and Gem's girlfriend Chantelle go into business with Vincent,Dushane,having got Raikes out of the way,is now the kingpin of the estate's drug-peddling industry, the Top Boy.
