Riko and Kane share a small East London flat while slipping deeper into a £15,000 debt owed to the Patels. They brainstorm increasingly desperate schemes to raise the money before the pressure from the crime family closes in. The setup establishes the high stakes that push their reckless plans forward.

They attempt to sell a mobile phone to two men on an East London street, but the buyers back away when they fear it could be a gun (Kane misreads the word 'strap'). The moment exposes their inexperience and the humiliating reality of trying to hustle money quickly. It raises the stakes by showing how far they still are from actually pulling off a heist.

For their second attempt, they target the rapper Lethal Bizzle in a public setting, hoping for a swift score. The plan backfires when they are knocked out, stripped, and ridiculed while a Link Up TV cameraman records everything. The humiliating footage goes viral, turning the duo into a laughing stock that follows them online.

Their third attempt is a bank robbery that spirals as they reveal their identities to the crowd. Leo ignores commands, taunts Riko, and then suffers a heart attack, collapsing as chaos erupts. Rumors spread that Riko shot Leo, earning him the nickname 'Rambo Riko' and catching the eye of gang leader Shotti.

Shotti takes notice of the chaotic events and assigns Riko, Kane, and Dwayne to retrieve a bag of drugs and money from a nightclub. The assignment marks a shift from petty crimes to organized gang work, with higher stakes and more dangerous players involved. The plan bonds the trio to the gang's inner circle for future jobs.

Riko becomes smitten with Tamara, which distracts him from the job and strains his loyalty. A fight breaks out with members of a rival gang, but Riko and Kane manage to win and escape. The encounter exposes the growing complications around trust and desire.

Riko explains his bipolar disorder to Dwayne, who reveals he is autistic, and the two form a bond over their shared vulnerabilities. They realize they forgot the bag at the club, throwing the retrieval plan into jeopardy. The consequences begin to ripple through their fragile operation.

Ian, a rogue police officer, and his partner Bill give chase, culminating in a car crash that leaves Riko and Kane detained while Dwayne escapes. The pursuit tightens the net around them and raises the tension for the next steps in the plan.

At the police station, Riko calls Tamara, and Leo wakes up from his heart attack to thank him, revealing he plans to quit gang life. Tyreese grows more furious and begins a vengeful hunt, even mistaking a policeman for Riko and running him over. Riko and Kane are released shortly after, heightening the fragility of their situation.

Back with Shotti, they admit they forgot the bag, which infuriates the gang leader and threatens their standing. A confrontation with a rival gang breaks out, but the crew manages to weather it and regain some footing within Shotti's orbit. The tension sets up the next warehouse job.

Shotti lets them tag along for a warehouse deal with Polish gangsters, drawing Tyreese's crew and Tamara into the plan. Riko reveals to Tyreese that he didn’t mean to hurt Leo, further straining his relationship with Shotti. The tension escalates as loyalties blur and risk rises.

The warehouse deal spirals into chaos as Ian and Bill arrive and poorly pose as Polish dealers, triggering a full-blown shootout. Riko is shot, Kane and Tamara help him escape while Dwayne knocks out Shotti and seizes his bag as police close in. DI Brookes later sacks Ian for going rogue.

The Patels break into Riko and Kane's home to reclaim their investment, but they only find the debt repaid in rupees, enraging the leader. Riko, Kane, Tamara and Dwayne decide to leave Britain for a new life in Los Angeles, cutting ties with their old world. The move signals a final shift toward a new start away from the Patels' reach.

In a police interrogation room during the post-credits moment, Shotti watches a social media video of Riko and Kane dancing with the money and glowers with annoyance. The scene underlines Shotti's continued obsession with their success and his anger at being outmaneuvered.
