Peaky Blinders: The Immortal Man

Amidst The Birmingham Blitz in November 1940, Nazi Germany initiates a plot to economically subdue the United Kingdom by introducing copious amounts of counterfeit British currency – manufactured by the inmates of the regime's concentration camps — into the British economy with the assistance of pro-Nazi agents, with the goal of triggering hyperinflation. Concurrently, a Luftwaffe night raid in Birmingham destroys a BSA munitions factory, killing the factory's female workforce.

Elsewhere, Tommy Shelby lives in isolation, having retreated from public life after the death of his elder brother Arthur, who supposedly died by suicide in December 1938. His only company is his loyal assistant Johnny Dogs. Tommy is working on his autobiography but is haunted by visions of his deceased daughter, Ruby. Ada Shelby, who has succeeded Tommy as the MP for Birmingham South, visits him to inform him of the acts committed by the Peaky Blinders, now led by his son Duke Shelby. Concurrently, the gang raids the destroyed factory and steals its munitions. In private, Duke has joined forces with Nazi agent John Beckett, who intends to have the Peaky Blinders distribute £70 million of counterfeit currency inside Britain through the gang's networks.

Meanwhile, Tommy is approached by Kaulo Chiriklo, the twin sister of Zelda Chiriklo – with whom Tommy had conceived Duke in 1914. Calling Tommy the Rom Baro, or the Gypsy King, Kaulo claims to have spoken to Arthur from beyond the grave, and goads Tommy into divulging that he had accidentally killed Arthur, who had acted erratically under the influence of opium. She nevertheless interprets Tommy's act as a kindness, and convinces him to return to Birmingham to save Duke, whom she deduces is in trouble. Elsewhere, Beckett discovers that Ada had collected testimony of Duke's raid at the factory and that she intends to submit it to the military police, which could derail the plot. He orders Duke to kill Ada, but Duke emotionally fumbles at the last minute; Beckett, who had anticipated this, kills Ada himself.

Tommy learns of Ada's death and confronts Duke, admonishing him for his ill-disciplined ways. He learns of the plot, and plans to kill Beckett at the mortuary where Ada's body is, deducing that Beckett would be there to kill him as well. At the mortuary, Tommy confesses to his deceased sister the true nature of Arthur's death: he had killed Arthur after becoming exasperated by his volatility. Beckett appears and tries to kill Tommy, but escapes after an exchange of gunfire. Meanwhile, Kaulo privately visits Duke and instructs him to ally with his father, but hands him a bullet inscribed with Tommy's name, ordering him to kill him after achieving their common goal.

Tommy, who has now reassumed his leadership of the Peaky Blinders, plans to use the arrival of the counterfeit money to defeat Beckett, with the assistance of his old allies Charlie Strong, Curly and dockyard boss Hayden Stagg – who has traced Beckett's car to a warehouse at the Liverpool docks. However, Duke reconnects with Beckett and promises to ensure the safe passage of the counterfeit money, as was previously agreed. Tommy plans to have the Blinders travel by narrowboat to Liverpool to confront Beckett's Nazi mercenaries, while he travels through a disused tunnel to surprise Beckett personally; both teams are to strike simultaneously at midnight.

Before leaving, Tommy has a private audience with Kaulo and reveals he is aware of her intentions, but does not explicitly oppose them. Beckett, who has been personally warned by Duke of the plan, has his forces intercept the narrowboats, not knowing that they are rigged with explosives. The resulting detonation kills the mercenaries; Duke reveals to a surprised Beckett that he had chosen to support his father all along, before escaping. The Blinders arrive and kill Beckett's remaining mercenaries. Tommy, who has arrived as well, uses a landmine to successfully incinerate the counterfeit money, thus suppressing the plot. Beckett tries to escape in his car, and exchanges gunfire with Tommy. Tommy is injured but kills Beckett, and attempts to die by standing in front of Beckett's speeding car, but Duke saves him.

Mortally wounded, Tommy encourages Duke to kill him with the bullet Kaulo gave him. Duke resists, but eventually obeys, and Tommy dies reciting the first line of the poem "In the Bleak Midwinter", having finally attained peace. Duke, now the new Rom Baro, leads the Peaky Blinders in conducting a Gypsy funeral for their fallen leader. Kaulo recovers Tommy's manuscript, The Immortal Man, in which Tommy reminisces that despite his wealth and power, he had his family by his side, and now in death is now reunited with them, wherever they may be.
