Plot
In 1979, during the height of The Troubles, Black British paratrooper Reuben James is attacked by IRA militants while leaving a pub in Northern Ireland. He is saved by fellow soldier and Londoner Tony, also known as "Fish." In 1982, Reuben and Fish fight in the Falkland Islands, along with another soldier from London, Bob Harper.
In 1988, Reuben leaves the army and returns to his old, poor neighbourhood in the East End of London. There, he is harassed by police officers, including the racist Challoner and Kilcoyne. Reuben's childhood friend Lynford still sells stolen goods and runs other small-time hustles. Another longtime friend, Colin, is now the local kingpin, selling drugs and bribing police. Fish, who lost his leg in the Falklands, is a gambler who cheats on his pregnant Irish wife, Debbie. Bob has become a policeman. Colin offers to make Reuben a part of his drug dealing operation, but Reuben declines.
Fish and Reuben attempt to celebrate Reuben's return to civilian life at a nightclub, but are turned away by the bouncer. The two get into a fight with security and spend the night drinking at Fish's flat instead. Returning home, Reuben finds his flat being burgled by children Oscar and Hayley. Reuben threatens Oscar, who points out Hayley's flat. Hayley's mother, Stacey, answers the door and denies that her daughter lives there. Reuben barges into the flat, looking for both Hayley and his belongings. Stacey threatens him with a knife to get him to leave. On his way out, Hayley comes home wearing Reuben's paratrooper beret, which he takes back. Stacey eventually finds Reuben's campaign medals and comes to his door to return them.
Reuben begins to look for a civilian job using his old army connections, but none of them returns his calls. Frustrated, he goes to a pub and meets Lynford. Challoner and Kilcoyne appear there and begin questioning Lynford about his whereabouts during a robbery. Lynford says he was with Reuben, who lies and confirms his story.
Reuben runs into Colin who takes him to see the legitimate business he has bought, a health club. Once again, Colin asks Reuben to join him, to no avail.
Bob and Fish come to Reuben's flat. Fish is flush from a big gambling win. Fish shows Reuben two tickets to Paris and says that he is taking Reuben on a trip, in part to thank him for covering an earlier debt with Bob. The three go to a party on the estate. There, Lynford thanks Reuben for backing him up with the police. Reuben again encounters Stacey; the two dance, and Reuben walks her home. En route, they are subjected to racist insults from officers. After reaching her door, Stacey kisses Reuben on the cheek. He returns to the party, which is raided by the police. Several of his friends, including Lynford, get arrested, but Bob tells him not to get involved.
The next morning, Reuben and Fish are at Reuben's flat. Reuben gets a phone call saying that Debbie has given birth early. Reuben takes Fish to the hospital, and Fish gives him both tickets, saying he will not be able to go now.
Reuben takes Stacey and Hayley to a funfair; there, he asks Stacey to go with him to Paris. She agrees until she sees Reuben playing a shooting game. This bring back memories of Hayley's father, who was a gangster who kept guns in the house, including in Hayley's cot. Reuben comforts an upset Stacey and says he was done with guns when he left the army. Returning home, Stacey offers to get Reuben a job, driving a minicab.
When they get back to the estate, there is a commotion going on. Three people bump into them, running away. One of them is Lynford, who has thrown a brick through a police car windscreen, killing constable Harry. Kilcoyne asks Reuben whether he saw anything, which he denies.
While preparing for the trip to Paris, Reuben applies for a new passport, but is rejected. He finds out that, since he was born in St Lucia, a change in British nationality law has stripped him of his citizenship.
Disillusioned, Reuben agrees to work as muscle for Colin. Carrying a hidden gun, he runs into Stacey. After discovering the gun, she leaves, furious. Colin and Reuben negotiate with another drug dealer, Sadiq, in a public toilet. The police later arrest Sadiq, as Colin has set him up. Returning to the estate, Reuben gives Colin back his gun and quits.
Reuben later finds Fish distraught, shooting up his own home with a rifle. Debbie has left him and taken the children to Ireland. Reuben gives him money and tells him to go after her. Reuben then comes home to find Kilcoyne in his flat. Kilcoyne knows about the deal with Colin and Sadiq, and threatens to send Reuben to jail unless he says who killed Harry. Reuben reluctantly gives up Lynford.
Wanting to leave behind his current life, Reuben gets a St Lucian passport and a ticket to St Lucia. Meanwhile, Lynford and others gather bats, knives, Molotov cocktails, and a gun, preparing to fight the police.
Lynford walks across the estate and the police chase him. From a walkway, someone throws a Molotov cocktail, starting a riot.
With his bag packed, Reuben runs into Fish in the lift. When the door opens, they find Lynford hiding from police on the ground floor. Lynford points his gun at Reuben and accuses Reuben of giving him up to the police, but Fish tackles him. Challoner and another officer rush through the door. Challoner panics and shoots Fish dead; Kilcoyne then runs in. Overcome with grief, Reuben goes to Fish's flat to retrieve his rifle. In the chaos of the riot, he shoots and kills Challoner. As he walks the estate holding the rifle, Reuben gets in the sights of a police sniper, who is actually Bob. After being ordered to take the shot, Bob then fires.
