In the bustling atmosphere of 1953 London, the iconic Agatha Christie play, The Mousetrap, is poised to celebrate its 100th performance. However, the event takes a dark turn when the disreputable American director, Leo Köpernick, is brought on by producer John Woolf to helm the film adaptation. Following a scandalous altercation with the lead actress, Sheila Sim, which culminates in a brawl with her husband, Richard Attenborough, Köpernick is mysteriously murdered backstage by a shadowy figure.
The ensuing investigation is led by the astute Inspector Stoppard, alongside the inexperienced yet eager Constable Stalker. As both delve into the depths of the theatre world, every person within the venue becomes a suspect, including the playwright’s keen producer, Petula Spencer, and Edana Romney, Woolf’s wife. Stoppard initially considers shutting down the theatre until the mystery is resolved, but his plans are interrupted by Metropolitan Police Commissioner, Harold Scott.
The detective duo searches Köpernick’s hotel room at the Savoy, discovering an intriguing address book filled with women’s names. The hotel manager recounts a heated dispute between Köpernick and the screenwriter Mervyn Cocker-Norris, who confesses to arguing about Köpernick’s vision for an action-packed film ending. Mervyn, residing with his fiery “nephew” Gio, recalls a “plain woman” accompanying Köpernick’s son during their stay.
The investigation takes a twist when they question Woolf, who had fallen victim to Köpernick’s blackmail after the director learned of Woolf’s affair with his assistant, Ann. Meanwhile, an usher named Dennis provides vague information regarding a suspicious figure. As the plot thickens, Spencer reveals that she had secured the film rights for The Mousetrap solely for Woolf, who is bound by contract from producing it until the play concludes.
During an evening at a pub, Stoppard candidly discusses his past with Stalker, disclosing that his wife left him after having a child with another man. This revelation leads to unexpected connections when Stalker uncovers a photograph of Stoppard’s ex-wife, lining up with Mervyn’s earlier description. This tantalizing clue casts suspicion on Stoppard, prompting Stalker to comb through Köpernick’s address book for further leads.
As the investigation unfolds, Stoppard and Stalker attend a performance of The Mousetrap. During this tense moment, Mervyn, Woolf, Dennis, Gio, and Stoppard exit the auditorium, with Stalker following closely behind as she witnesses Stoppard retrieving his gloves. In a tragic turn of events, Mervyn is brutally murdered by an unidentified assailant. Stalker misinterprets the scene, knocking Stoppard unconscious in her haste to apprehend what she believes to be the murderer.
Regaining consciousness in a holding cell, Stoppard is shocked to find himself accused of the murders by Stalker and Scott. In a twist of fate, Stalker locates Joyce, the mother of Köpernick’s son, who ultimately confirms that she is not Stoppard’s ex-wife, clearing his name. As the investigation further escalates, Joyce reveals overhearing someone speaking with a peculiar “village idiot” accent, which becomes an essential clue.
Through painstaking examination of Mervyn’s research regarding The Mousetrap, Stoppard ultimately deduces the identity of the real killer and races to the suspect’s location just as Stalker discovers critical evidence pointing to Dennis’s guilt.
In a climactic confrontation at Agatha Christie’s residence in Wallingford, Berkshire, Stoppard, Sim, Woolf, Ann, Spencer, and her mother find themselves held at gunpoint by Dennis, who possesses a chilling backstory linked to the tragic inspiration for the play. In an explosive finale, the stage transforms into a battleground, complete with deception and a showdown involving a poisoned cup, mistaken identities, and life-threatening heroics.
Through the chaos, Stalker displays her bravery as she risks her life in the name of justice, while Stoppard bravely confronts the threats posed by Dennis, ultimately leading to a resolution that sees him injured but triumphant. As time passes, Stalker triumphs in her sergeant’s exams, while Stoppard receives the esteemed King’s Police and Fire Services Medal. They rekindle their bond by attending another performance of The Mousetrap, illustrating the persistence of resilience in the face of darkness.

Explore frequently asked questions about See How They Run (2022) with spoiler-rich answers covering the full plot summary, major story beats, character motivations, hidden details, and ending meaning. This movie summary FAQ helps explain confusing scenes, plot twists, and narrative decisions in clear, searchable detail.
Leo Köpernick was murdered by Dennis, the theatre usher. Dennis reveals during the climactic confrontation at Agatha Christie's residence that he is the son of a woman whose tragic story inspired Agatha Christie to write The Mousetrap. Feeling that his mother's story was stolen and exploited for profit, Dennis sought revenge against those profiting from the play.
Earlier in the film, Dennis provides vague information about a suspicious figure to the detectives, which hints at his involvement.
Dennis killed Leo Köpernick because he blamed the theatre world and everyone connected to The Mousetrap for exploiting his mother's tragic story. His mother had been the real-life inspiration for the play, and Dennis believed Agatha Christie and those profiting from the adaptation had stolen his family's pain for financial gain.
Dennis also murdered Mervyn Cocker-Norris during a performance of The Mousetrap. After Köpernick's murder, Dennis killed Cocker-Norris to silence him because Cocker-Norris had been conducting extensive research on the play's origins for his screenplay, which threatened to expose the truth about the murder's inspiration.
Mervyn's murder occurs right after Stoppard and Stalker attend The Mousetrap performance, with multiple suspects leaving the auditorium.
Stoppard was arrested because Constable Stalker misinterpreted the scene at The Mousetrap performance. When Mervyn was murdered, Stalker saw Stoppard retrieve his gloves from the floor and exit the auditorium, leading her to believe he was the killer. Combined with the discovery that Stoppard's ex-wife matched the description of a woman in Köpernick's address book, the evidence seemed damning enough to arrest him.
Stoppard's earlier confession to Stalker about his wife leaving him for another man becomes a crucial piece of circumstantial evidence used against him.
Dennis is the son of a woman whose tragic real-life story inspired Agatha Christie to write The Mousetrap. His mother suffered greatly, and Dennis believed Christie and the theatre industry exploited her pain for profit. This personal grievance drove him to kill anyone connected to the play's film adaptation, which he viewed as another exploitation of his family's tragedy.
The connection was a red herring. When Stoppard revealed to Stalker that his wife left him after having a child with another man, Stalker discovered that Köpernick's address book contained the name of a woman matching Stoppard's ex-wife description. This initially cast suspicion on Stoppard. However, Joyce, the mother of Köpernick's son, later confirmed she was not Stoppard's ex-wife, clearing his name.
Stoppard's personal revelation at the pub about his wife's affair becomes the misleading clue that almost incriminates him.
John Woolf was being blackmailed by Leo Köpernick because the director discovered Woolf was having an affair with his assistant, Ann. Köpernick used this information to leverage Woolf into allowing him to direct the film adaptation of The Mousetrap, despite Woolf's initial reservations about bringing on a controversial director.
Joyce, the mother of Köpernick's son, overheard someone speaking with a distinctive "village idiot" accent at the time of the murders. This peculiar detail became a key clue that helped Stoppard identify Dennis as the killer, as Dennis's speech pattern matched this description when he was finally confronted.
At Agatha Christie's residence in Wallingford, Dennis holds Stoppard, Sim, Woolf, Ann, Spencer, and her mother at gunpoint. He reveals his backstory and motive before a chaotic showdown ensues. The stage transforms into a battleground with deception, a poisoned cup, mistaken identities, and life-threatening heroics. Stalker risks her life to stop Dennis while Stoppard confronts him, resulting in Stoppard being injured but ultimately triumphant.
The altercation began when Köpernick, known for his disreputable behavior, confronted lead actress Sheila Sim backstage. The confrontation escalated into a heated argument, which drew the attention of Sheila's husband, Richard Attenborough. The situation deteriorated into a physical brawl involving all three, occurring right before Köpernick's murder and making everyone in the theatre a suspect.
Still wondering what the ending of See How They Run (2022) really means? Here’s a spoiler-heavy breakdown of the final scene, major twists, and the deeper themes that shape the film’s conclusion.
The ending of “See How They Run” reveals that the true culprit behind Kopernick’s and Mervyn’s murders is Dennis, the usher who had a deep personal connection to the story that inspired “The Mousetrap.” Dennis had lost his brother in a real tragedy and believed the play, which was based on his life, was exploitative and mocking his pain. His anger grew over the years as he watched the story being turned into a theatrical and cinematic spectacle, feeling that his grief was being profited from and trivialized. When Kopernick, the film director, began creating a climax that mirrored the original story of Dennis’ life but with added violence, Dennis saw it as a final insult and decided to take revenge. He murdered Kopernick and later Mervyn, who shared ideas with Kopernick and was involved in the film’s development.
However, the chaos reached its peak when Agatha Christie herself intervened. She cunningly offered Dennis poisoned tea, trying to calm him down and prevent further violence. Unfortunately, Dennis, in his desperation, seized Christie as a shield and almost caused more destruction. Stoppard and Stalker, the detectives, eventually uncover Dennis’ motive through clues he inadvertently left behind. They learn that Dennis felt betrayed and misunderstood, believing that the art based on his tragedy had been perverted to mock his suffering. Ultimately, Dennis’s rage culminated in a tragic shootout, where he held Christie hostage and was finally shot by Stoppard when he threatened to kill others, including himself. The film ends with Stoppard breaking the fourth wall, telling the audience not to reveal who the killer is, emphasizing the classic whodunit style.
In the final moments, Christie’s dinner at her house symbolizes that beneath the glamour and theatricality, real pain and unresolved trauma can still lie hidden. The story ultimately questions whether an artist’s creative liberties justify exploiting true human suffering, and whether society is willing to tolerate the uncomfortable truths that such stories may reveal. Dennis’s tragic story underscores the importance of respecting the line between art and reality, and how misusing personal tragedy can lead to devastating consequences. The ending leaves viewers pondering the blurred boundaries between fiction and life, morality, and the costs of artistic expression.
