John Avery, Anthony Hopkins, and his supervisor LeClerc, Ralph Richardson, find themselves entangled in a high-stakes Cold War ruse after an MI6 agent is killed and a roll of flyover photographs goes missing. The initial discovery suggests the Stasi are concealing a new rocket system based on the V-2, a potential violation of international accords. When a second source delivers photographs that supposedly confirm the rocket’s existence, the MI6 team pays for the set, only to learn that the images are said to be held in Kalkstadt by the source’s father. With this hint, the agency crafts a daring plan: to verify the rocket by sending one operative across the East German border, a mission that hinges on trust, timing, and a delicate political balance.
Leiser, a Polish defector and Christopher Jones who has illegally entered England to be with the woman who bears his child, is vetted for the mission and granted a potential path to UK citizenship in exchange for his service. He undergoes intense preparation at a safehouse, learning self-defense, survival skills, and how to use a compact radio transmitter to send coded updates. His resolve wavers when a private reunion with his girlfriend reveals a painful truth—their child was aborted—yet a night of shared camaraderie with Avery rekindles his determination to proceed.
Crossing the border under the cover of darkness, Leiser endures a brutal start: a severe hand injury from barbed wire, and, later, he is forced to kill a young East German border guard who glimpses his presence. The news of the killing ricochets through the morning papers, intensifying the spotlight on the mission. A series of dangerous twists follows: a lorry driver offers a ride that ends with betrayal, and Leiser must kill again to survive when the driver makes inappropriate demands. He presses on, guided by a West German cabin’s monitoring team who track his coded transmissions, while a local girl and her young friend secretly assist him before the lorry is submerged in a lake and he is left to fend for himself.
Meanwhile, in Kalkstadt, Leiser reaches the destination only to confront a stark truth: the photographs never existed, and the entire setup was a con by MI6’s source. Feverish from the infected wound and physically depleted, he attempts to leave but is intercepted by the Stasi, who learn of his West-to-East crossing. They detain him at a hotel, while the girl he met earlier reveals her own knowledge of his origins and a wish to escape with him. That night, MI6 orders the operation shut down due to the international incident it has sparked, yet Leiser witnesses a legitimate East German rocket being transported through the town’s streets. He communicates this discovery over the radio, but the Stasi triangulate his location, and he and the girl are shot down.
Back at the West German cabin, Avery confronts the moral toll of the operation: LeClerc reveals that Leiser was treated as expendable from the start, supplied with an obsolete radio to feign independence, and deliberately denied a pistol so the West could avoid an outright act of war. The overall plan appears to have been an elaborate bluff designed to provoke a Western response rather than to secure a genuine weapon. In a somber coda, the roll of film is recovered by children who, unaware of its significance, destroy it while playing, erasing the only physical trace of the operation’s supposed proof and underscoring the fragility and deception of Cold War theater.
Across the narrative, the human cost of espionage is laid bare: the personal losses, the blurred loyalties, and the perilous ambiguity of intelligence work. The film juxtaposes the sterile precision of spy craft with the messy, sometimes tragic, consequences that ripple outward from every decision. The cast’s performances add shaded depth to a story that moves from calculated risk to quiet tragedy, leaving the viewer to ponder what might have happened if even a single variable had shifted.
- Avery’s wife, Anna Massey, makes a quieter, supporting appearance in the wider arc of Avery’s personal life, highlighting the distance between private life and public duty.
- The cast also includes a range of colleagues and on-the-ground players who populate the world of MI6 and Kalkstadt, each contributing to the atmosphere of a tense, morally complex espionage drama.
- The final image suggests that the East German rocket, if it existed at all, may have been a bluff designed to provoke a response, leaving the film’s central mystery unsolved and the moral questions lingering.
Overall, the story blends suspense, political subterfuge, and character-driven drama to present a nuanced, somber portrait of Cold War espionage. The pacing builds gradually through moments of action, misdirection, and emotional revelation, culminating in a somber coda that questions the value and purpose of high-stakes intelligence operations.
