In Moscow, USSR, the film opens with a serene and joyful scene of three young individuals gliding gracefully across the frozen pond of Gorky Park, embracing the joys of winter. However, this peace is shattered just three days later when the lifeless bodies of these young people are discovered, brutally shot at close range, with their faces and fingerprints meticulously removed using surgical tools. The investigation falls into the hands of Arkady Renko, portrayed by William Hurt, a diligent officer with the Soviet militsiya, who finds himself grappling with an unnerving sense of paranoia and anxiety as the KGB declines to take control of the case. To aid him in unveiling the mystery, Renko seeks the expertise of Professor Andreev, played by Ian McDiarmid, who endeavors to reconstruct the victims' faces.
As Renko delves deeper into the investigation, he encounters William Kirwill, a dedicated detective from New York, portrayed by Brian Dennehy, who has traveled to the Soviet Union in search of his missing brother, James. Their paths intertwine during a weekend retreat at the dacha of Chief Prosecutor Iamskoy, represented by Ian Bannen, where Renko also meets the charming Jack Osborne, a sable importer, played by Lee Marvin, and his enigmatic girlfriend Irina Asanova, depicted by Joanna Pacula.
Slowly but surely, Renko pieces together the identities of the victims: James Kirwill and two young Russians who were friends of Irina. He uncovers that their tragic fate was linked to the construction of a chest for Osborne, intended for the illicit smuggling of six sables out of the country— a plan that could jeopardize the Soviet monopoly on their lucrative fur. As he converses with Osborne, Renko becomes increasingly suspicious of him, especially amidst their tense yet polite encounters.
The plot thickens when Irina is ambushed by a KGB agent who attempts to administer a lethal dose of drugs. In a dramatic rescue, Renko saves her life, and in the seclusion of his apartment, a tender relationship blossoms between the two. Irina, however, remains resolute in her belief that her friends have survived, clinging to Osborne's assurances that they would be freed in exchange for their labor.
As time unfolds, Renko is forced to confront the grim reality. He brings Irina face to face with Professor Andreev's reconstructed likeness of one of her friends, compelling her to acknowledge the horrific truth of their murders orchestrated by Osborne. In a moment of desperation, she divulges critical details about the conspiracy before fleeing, leaving Renko and Kirwill in pursuit of further answers.
Their investigation leads them back to Andreev's, only to have their hopes extinguished when a KGB agent appears with a box containing the second reconstructed head, drawing them back to Iamskoy's dacha. From a distance, they witness the chilling scene of Osborne and Iamskoy monitoring the destruction of the evidence—a revelation that reveals the identity of the head to be that of Kirwill's brother.
In a tense confrontation in a bathhouse, Iamskoy reveals that Renko's relentless investigation was a machination to coerce Osborne into a higher payoff for the sables. Offers of corrupt partnerships are met with defiance when Renko reveals he has recorded the conversation. Chaos ensues, leading to Iamskoy's unintended demise during a struggle, further entangling Renko in this deadly web of deception.
With Osborne fleeing to Stockholm, Sweden, the KGB permits Renko to follow him under the pretense of overseeing an exchange. Arriving in a bedroom, he discovers Irina, who confesses her betrayal—having aligned herself with Osborne under the guise of a freedom deal for both of them. Renko, feeling the weight of betrayal, retaliates with disgust, asserting that she carries the blood of the innocent on her hands.
The plot culminates in a harrowing showdown on a remote farm. The shocking discovery of Kirwill's grotesquely mutilated body sends Renko into despair as Osborne exclaims the grisly details of the murder. In the standoff that ensues, Renko recognizes an impending doom; neither party is willing to leave the locale alive. As tensions rise, Irina emerges amidst the chaos, and a gripping moment unfolds when she shoots Osborne, followed by Renko, leading to Osborne's demise.
With Irina poised to escape into freedom, Renko faces the heart-wrenching choice of letting her go while releasing the captive sables into the wild. As they flee into the woods, echoing in his mind is Irina's voice, pledging that they shall meet again in the future, leaving a poignant and lingering sense of hope amid the brutal realities they've faced.
