The fourth episode of Gangs of London's thrilling third season kicks off with Luan pledging vengeance against those who have crossed him—Billy Wallace and Cornelius foremost among them. His wife, though, harbors doubts, whispering that perhaps Elliot had a point, yet Luan's heart is unyielding, consumed by a relentless thirst for retribution.
Meanwhile, amidst the solemnity of Sean's funeral, Marian stands immersed in grief, when Ed makes an unexpected appearance, cautioning Billy and Cornelius to steer clear of the church lest they invite trouble to their doorstep. Elsewhere, Simone relays crucial intelligence to Elliot, urging him to track down the mysterious white van that was flagged down for a routine check in the previous episode. This van, piloted by Lale, had undergone a plates swap at a nearby dealership, prompting the need to uncover its new identity.
Elliot, accompanied by a reluctant Shannon, storms into the dealership, demanding answers with a ferocity that borders on brutal. He subjects the dealership employee to a grueling interrogation, extracting the van's registration details only after a harrowing ordeal. Shannon, witnessing this harsh tactics, is less than impressed.
The revelation that Lale serves a higher master comes to light when she receives a phone call, murmuring that she assumed "they had taken care of it." This hint at a deeper conspiracy adds another layer to the narrative.
Outside the funeral, designated as a "family-only" affair, Luan lurks in the shadows, his eyes burning with intent. Zeke arrives, paying his respects to Sean and confiding in Marian that he knew the deceased and believed Sean's fate was unjust. Marian, while accepting his condolences, firmly reminds him of the event's exclusive nature.
Inside the hushed sanctuary, Billy and Cornelius daringly make an appearance, unaware that their steps have led them into a trap. Luan and his henchmen, anticipating an attack, launch a preemptive strike, intending to catch their adversaries off guard. The church, meant to be a sanctuary of peace, transforms into a battlefield as loyalty, betrayal, and vengeance intertwine in a harrowing dance of power and survival.
Eventually, the dramatic climax unfolds as Luan succeeds in seizing Marian, holding her hostage under the threat of his gun. Though vastly outnumbered, Luan remains unchallenged until Billy courageously steps forward to confront him. However, his aim proves faulty, allowing Luan to slip away from the tense confrontation.
Luan hastily returns to his home, gathering his family in what turns out to be a fortuitous decision. Shortly thereafter, Marian and her allies arrive at his estate, seeking vengeance for the church attack. With the Wallace faction hot on their heels, Luan and his family narrowly escape into the dense woods bordering their property.
Elsewhere, Elliot meticulously traces the registration to an abandoned warehouse, where Lale is diligently shifting beer kegs between vans. She subsequently drives off to a nearby parking lot, where her assassin counterpart takes over the operation. Despite Elliot's relentless pursuit, he arrives too late to intercept Lale, who speeds off into the unknown. Elliot's attention is then drawn to a logo emblazoned on a nearby yellow door, recognizing it as the same insignia from the files stolen during his wife's fatal night.
Back at the office, the Mayor's assistant, Henry, expresses astonishment at Simone's collaboration with criminals like Elliot to curb gang activity. He reminisces about her campaign promise to eradicate all drugs, noting her apparent reversal of stance. Nevertheless, the idea now seems an alluring alternative.
Concurrently, Cornelius confronts Ed, sternly warning him against offering guidance to Marian. The animosity between them is palpable, and as the episode draws to a close, Elliot finds himself in a confrontational standoff with Zeke, who has cleverly stacked the beer kegs in his house to frame himself as the scapegoat.
