In the politically charged atmosphere of 1980s Cold War London, Fleet Street is a battleground of ambition, rivalry, and relentless deadlines. At the heart of this cut-throat world is Nick Mullen, a young, ferociously ambitious reporter for the Daily Despatch. Mullen is driven by a burning desire to make a name for himself, to break the one big story that will catapult him to the top of his profession. He is sharp, cynical, and initially unconcerned with the moral complexities that may lie beneath a sensational headline.
His world is shared by Vernon Bayliss, a veteran journalist of the old school. Where Mullen is rash and hungry for glory, Bayliss is weary, methodical, and haunted by the compromises he has witnessed throughout his long career. He serves as a reluctant mentor and a cautious sounding board for Mullen's explosive energy, their dynamic a classic clash of youthful fire and aged wisdom, bound by a shared, albeit sometimes begrudging, respect for the craft.
The film ignites when Mullen receives a tantalising tip from an anonymous source. The information points to a major sex scandal involving Dennis Markham, a respected Member of Parliament who has been a vocal critic of the government's close military relationship with the United States, particularly regarding the presence of American nuclear forces on British soil. The story is explosive: Markham has allegedly been frequenting a London club where he has been meeting with a call girl who is also a suspected KGB agent. For Mullen, this is the scoop he has been waiting for. He pursues it with vigour, and the subsequent front-page exposé creates a political firestorm, effectively destroying Markham's career and reputation overnight.
Initially, Mullen basks in the glory of his journalistic triumph. However, the neat narrative soon begins to fray at the edges. Small inconsistencies and lingering questions trouble Bayliss, who, with his seasoned eye for detail, starts to believe that the story was too perfect, too easily handed to them. He quietly begins his own discreet investigation, urging a dismissive Mullen to consider the possibility that they have been used as pawns in a much larger, more sinister game. Mullen, still high on his success, initially resists Bayliss's cautious counsel, viewing it as the ramblings of a man who has lost his nerve.
The tone shifts dramatically when Bayliss dies suddenly and mysteriously in what is officially ruled a heart attack. Stricken with guilt and a growing sense of dread, Mullen is shocked into action. He discovers that Bayliss had been secretly investigating a seemingly unrelated event: a near-disastrous accident at an American airbase in the UK. Retrieving Bayliss's hidden research, Mullen inherits his mentor's investigation and his paranoia. He begins to piece together the terrifying truth that the Markham scandal was not about sex, but was an intricately fabricated smear campaign designed to silence him.
As Mullen delves deeper into the labyrinthine cover-up, the shadows begin to close in. He finds himself under constant surveillance, his flat is ransacked, and his every move is seemingly anticipated by faceless, powerful forces within the state's security apparatus. The story he is chasing is no longer about journalistic ethics or a political scandal; it is about a chilling government conspiracy to conceal a near-nuclear catastrophe from the public. Every new lead and every potential source becomes a risk, pushing Mullen further into a dangerous isolation where the very institutions meant to uphold the nation's defence are the ones he has to fear the most. He is no longer just a reporter chasing a story; he is a man fighting for his life against an enemy he cannot see.
