The episode unfolds at the residence of Alan Rusby (portrayed by Nigel Lindsay), where Kevin Harrigan (played by Paddy Considine) rambles on nervously about his deepest fears concerning Conrad Harrigan (Pierce Brosnan) and Maeve Harrigan (Helen Mirren). Rusby's lifeless body slumps over the dining table, a grim testament to the unfolding drama.
Kevin paints Maeve as a stealthy shark, lurking beneath the surface before striking with relentless ferocity. He reveals that Eddie Harrigan (Anson Boon) is his flesh-and-blood brother, not a son, and shares his knowledge of Bella Harrigan's (Lara Pulver) illicit affair with Conrad, branding her as his cast-off lover. He speaks of his attempt to lead a humble existence for Eddie's sake, despite emerging from prison with his pride shattered. However, he couldn't escape Maeve's influence, which twisted him into a monster akin to her. Maeve, he claims, manufactures monsters to safeguard the Harrigan dynasty, and he partially blames Rusby for his own monsterous transformation.
In the jail's processing area, Conrad and Maeve await their fate. Meanwhile, Harry Da Souza (Tom Hardy), Zosia (Jasmine Jobson), and Kiko (Antonio Gonzalez Guerrero) arrive to discreetly dispose of Rusby's corpse and eradicate any incriminating evidence. Elsewhere, Paul (Emmett J Scanlan) orchestrates the transfer of Bella, Eddie, Jan Da Souza (Joanne Froggatt), Seraphina Harrigan (Mandeep Dhillon), and Gina Da Souza (Teddie Allen) to a secure hideout in Guildford. Rusby's body is zipped into a body bag, marking the conclusion of one chapter and the beginning of another.
At the yards, Harry beckons O'Hara Delaney (Lisa Dwan) to take a seat, his tone serious and demanding. He underscores the importance of her honesty in answering his questions. She confesses to initiating contact with Richie Stevenson (Geoff Bell), though her trust in him wavers. When pressed if Richie used her intel to harm the Harrigans, she reluctantly admits he did. She denies informing Richie about Antwerp or Archie Hammond (Alex Jennings), insisting their meeting remained her secret. Harry suggests her betrayal stemmed from fear of Richie, to which she nods in agreement. He dismisses her with a promise to call her later.
Shortly after, Harry shares Delaney's confession with Kevin. Kevin, in turn, inquiries about Harry's awareness of his prison ordeal. Harry, though unaware of the specifics, reveals he already knew Kevin wasn't Eddie's father, thanks to Bella's revelation. He urges Kevin to stay focused on their mission. Kevin assures him he's got it under control before exiting the scene.
In Guildford, Eddie receives a cryptic text, purportedly from Maeve, urging him to sneak to Oakpark Prison without alerting anyone. Bella catches a glimpse of his departure. At Oakpark, Conrad exudes confidence, believing O'Hara will expedite their release. Kevin drops a bombshell, revealing it was O'Hara, not Archie, who supplied Richie with incriminating information. He voices his resentment towards Conrad for the damage inflicted upon him and demands accountability for Eddie. He vows to carve his own niche, promising Conrad a front-row seat to witness his rise. Conrad, in a moment of sarcasm, mocks Bella's intimate parts, prompting Kevin to caution him about the perilous company he keeps. Conrad feigns terror, but Kevin stands firm, asserting that upon their release, they'll enter a world where everyone pays dearly for their actions. Conrad, enraged, repeatedly slams the phone against the glass partition, echoing the tension and conflict that permeate this dramatic saga.
In the heart of Guildford, Bella shared with Gina the news that Eddie had departed, leaving a trail of uncertainty in his wake. Gina's curiosity piqued, she inquired whether Eddie was angry. Bella, hesitant, recounted memories of Eddie's former joy, a state marred by Maeve's influence. Gina pondered aloud, wondering if Eddie could ever reclaim his happiness. Bella shook her head, insisting that reverting to their former selves was an impossibility.
Meanwhile, at Oakpark, Maeve approached Eddie with grim tidings, revealing that Harry had sanctioned Alice's departure and that she and Seraphina were orchestrating a coup. With a cold command, she ordered Eddie to eliminate Harry first. Scanning the lobby, Maeve declared their reign as king and queen. Eddie, confused, reminded her of their familial bond. Pretending astonishment, Maeve questioned his ignorance. Eddie, baffled, sought clarification, only to leave shortly thereafter, his mind a whirl.
Elsewhere, Seraphina conveyed her gratitude to Kat McAllister over the phone, thanking her for saving her life. Kat, revealing that Conrad's power had waned, extended an invitation to lunch to discuss their future. Seraphina eagerly accepted.
In a secluded locale, Colin Tattersall informed Alice of a sinister plot, revealing that Conrad's DNA had been planted on the murder weapon used to slay DS Ivan Fisk and DC Mukasa, while Maeve's DNA had been incriminatingly left on the victims. Alice, seeking closure, asked if it was all over. Tattersall handed her a backpack filled with $100,000, boasting about his meticulous crime, a throwback to old-school heists. Suddenly, two men approached the vehicle. In a hurry, Tattersall grabbed his thermos and exited, leaving Alice vulnerable. A man slipped into the backseat, placing a drugged cloth over her face. She fought momentarily before succumbing to its effects. Tattersall swiftly informed Richie of their success.
During a tense phone conversation, O'Hara informed Harry that Richie had visited her office, flanked by two henchmen. She relayed Harry's orders and, upon ending the call, warned Richie that Harry was privy to their agreement. Later, at The Sinful Monkey, Richie confronted O'Hara, questioning why Harry had spared her life. She explained that Harry sought to lure him into a trap at her office, using her as bait. Richie, skeptical, demanded proof of her loyalty. With a gun pressed against her throat, she contacted Harry, confirming the meeting. Harry, cautious, questioned her motives. She reiterated their shared victory, soothing his doubts. He thanked her and ended the call, prompting her to urge Richie to strike at the Harrigans' Guildford safe house. He dispatched Olie Donker to her office and Charlie Sweet to the safe house, ordering them to leave no survivors. Charlie and Olie, each leading armed teams, prepared for the deadly assault. Kevin and Harry, unaware of the impending danger, departed the yards.Staked out at O’Hara’s office, Paul witnesses a car screeching to a halt. Olie, accompanied by several armed men, steps out and makes their way into the building, leaving the car to speed off into the distance. Once inside, Olie promptly informs Richie of their arrival.
Meanwhile, at The Sinful Monkey, O’Hara alerts Harry that she is at her office, revealing that Richie is left alone. She then informs him that both she and Kevin are making their way to her office. Richie, in turn, alerts Olie that Harry will arrive within two minutes. In response, Olie and his armed companions cock their weapons, ready for action.
Elsewhere, in Guildford, Bella watches a live news report featuring Lord Pennock (Steven Pacey) vehemently denying the allegations of illegal lobbying and bribery. Suddenly, Eddie bursts in, accusing her of sleeping with Conrad, a claim substantiated by Maeve. Eddie insists that Bella follow his instructions from now on. As he rubs his cheek, Bella professes her love for him, embracing him and apologizing. However, her gesture is met with a chokehold from Eddie, who vows that no one will ever lie to him again. Bella struggles to free herself, swatting at him and begging him to stop. Just then, Kiko strikes from behind, grabbing Eddie by the throat. Bella hastily orders Kiko to release him, who then shoves Eddie into the hallway. Zosia knees him and demands to know the whereabouts of the others, but Bella is clueless. Eddie bends over in pain, just as a vehicle pulls up outside. Charlie and his armed men emerge, entering the house to find it deserted. He immediately notifies Richie.
Back at O’Hara’s office, Olie notices Paul lurking near a walkway tunnel. Sarcastically calling himself Paul “Nine Inches” O’Donnell, Paul pretends to switch on Christmas lights using a remote, but nothing happens. Inside the building, a beeping sound alerts Olie to danger. Holding the remote outside the tunnel, Paul presses the button, causing O’Hara’s office and several others to explode in a fiery blaze. With a sinister smile, Paul walks away from the scene.
At The Sinful Monkey, Richie demands an explanation from O’Hara, who admits to lying when she said he was smarter than Harry. In Guildford, Seraphina, Bella, Gina, and Jan are hiding in the woods when they witness the safe house explode in a fiery inferno. Panicked, they take off running for their lives. Inside the house, some of Richie’s men survive the blast but are quickly gunned down by Zosia and Kiko. An injured Charlie manages to shoot Kiko before being riddled with bullets by Zosia.
Kevin and Harry storm into The Sinful Monkey, their weapons blazing as they unleash a hail of bullets upon Richie's men. Richie, with O'Hara held captive at gunpoint, watches helplessly as the door bursts open and the assault begins. O'Hara, caught in the crossfire, falls wounded to the ground. Richie, too, becomes a target and collapses under a rain of bullets, his body hitting the floor with a thud. Eddie leans over him, commanding him to look into his eyes. With compliance, Richie meets his gaze, only to hear Eddie whisper, "The Harrigans send their regards," before delivering the final shot. Harry steps forward to ensure O'Hara's fate is sealed.
Meanwhile, in Oakpark, Maeve receives a cryptic message on a disposable phone: "The war is won." She hastily dials Conrad's number, but instead of relief, she faces his scolding and vile names. Calling herself an unfeeling, barbaric Mother Nature beloved by all, she confesses to putting people to the test, seeking out those who possess "it." Despite her harsh self-assessment, Conrad professes his undying love for her.
Elsewhere, Kevin and Harry listen to an audio recording of Alice, revealing that Conrad did not kill Fisk and Mukasa. Harry believes this evidence will be sufficient to clear their names, while Kevin suggests keeping their adversaries imprisoned for a few more weeks. Recognizing the need for legal counsel, Harry insists on finding a competent attorney.
In Guildford, Zosia sits in desolate silence beside Kiko's lifeless body, her heart heavy with grief. Back at O'Hara's office, Tattersall surveys the grim aftermath, while forensic experts meticulously process the crime scene.
Kat approaches Harry, informing him of Conrad's resurgence and hinting at Kevin and Seraphina's potential defiance. She seeks his advice on how to dismantle the Harrigans' power, but he stands firm in his loyalty. Kat tempts him with an alliance or friendship, but he rejects her offers, prompting her to threaten his family. Harry responds with a blunt dismissal, earning a stern warning about the gravity of his choice.
At Cotswold, Bella updates Kevin on Pennock's arrest, querying if it serves her purposes. She denies any personal gain, revealing that Kevin's sleep-talking revealed Pennock's years-long abuse of her as a child.pledging her unwavering support to Kevin. Grateful for her bravery, Kevin expresses his thanks.
Harry visits Jan, informing her of Richie's demise and promising a new beginning. Jan, weary of the perpetual danger, laments her perilous existence with Gina, accidentally stabbing Harry with a kitchen knife in a moment of frustration. Harry remains calm, inviting her to voice her grievances, now that she has his full attention.
Back in Oakpark, inmates cheer Conrad's return to power, as he joins in the festivities, basking in his triumph.
