Netflix Just Added an 86%-Rated WWII Movie About a True Story That Sounds Almost Impossible
A young Polish woman hiding 12 Jewish workers in the home of a German officer sounds like the setup for a wartime thriller. In Irena’s Vow, it is the central reality of a story that actually happened.
The film follows Irena Gut Opdyke, a Polish woman working under Nazi occupation during World War II. With no military background and very little power, Irena finds herself in a position where small acts of resistance can mean the difference between life and death.
Her most dangerous decision is also the most astonishing: she hides Jewish people inside a villa occupied by a German officer.
Irena’s Vow arrived on Netflix on August 31, 2026, and the film currently carries an 86% Tomatometer score from critics on Rotten Tomatoes. Directed by Louise Archambault and led by Sophie Nélisse, the 2024 historical drama turns Irena’s wartime experience into a tense story of survival, secrecy and courage.
The film originally premiered at the 2023 Toronto International Film Festival. It later won the Audience Award in the Panorama section at the 2023 Vancouver International Film Festival, as well as the LIUNA People’s Choice Award at the Windsor International Film Festival.

Netflix currently lists Irena’s Vow among its WWII movies and films based on real life.
The Extraordinary True Story Behind Irena’s Vow
The story begins with Irena Gut Opdyke, a young Polish Catholic woman living under German occupation.
During the war, Irena worked in a laundry associated with a German officers’ club, where she supervised Jewish workers. She secretly helped them by providing food and other necessities. As Nazi persecution intensified and the camp was liquidated in 1943, the risks surrounding her became far greater.
Irena began helping Jewish people find places to hide. She maintained contact with people concealed in a bunker in the forest and helped others hide in locations connected to her work.
Eventually, she concealed 12 Jewish workers inside a villa that had been requisitioned by German Major Eduard Ruegemer.
That decision created an almost unbearable situation. The people Irena was trying to protect were hiding inside a property where German officers could appear at any moment.
The premise may sound too improbable for a historical drama, but the central events are rooted in Irena’s real wartime experience. Yad Vashem records Irena Gut Opdyke among those recognized for helping Jews during the Holocaust.
The film compresses this complicated history into a focused survival story. Irena must continue providing food and protection while dealing with the constant possibility that the people hidden around her will be discovered.
The official synopsis gives the story’s central dilemma even more directly: at 19, Irena becomes a housekeeper in the home of a German officer and learns that a Jewish ghetto is about to be liquidated. She then decides to hide 12 Jewish workers in the basement of the German commandant’s house.
Over the following two years, the danger does not disappear. Irena has to keep the people hidden while Nazi officers continue to occupy and visit the house. The film also incorporates a blackmail scheme, Nazi parties and the birth of a child into the increasingly complicated circumstances surrounding her secret.
The real Irena survived the war, as did many of the people she helped. Decades later, survivors invited her to Israel, where she was formally honored by Yad Vashem for risking her life to save Jews during the Holocaust.
Sophie Nélisse Gives the Story Its Human Center
A remarkable true story does not automatically translate into a compelling movie. Much of Irena’s Vow depends on Sophie Nélisse’s performance as Irena.
Nélisse portrays Irena as a young woman who is frightened by the world around her but repeatedly forced to make decisions that become more dangerous. Rather than beginning as an action hero, Irena gradually becomes more resourceful as the circumstances around her deteriorate.
That progression gives the character a human quality. Her courage comes through decisions made under pressure rather than through conventional displays of heroism.
Critics have also singled out Nélisse’s performance. RogerEbert.com’s Christy Lemire gave the film three out of four stars and praised the subtlety of Nélisse’s work, particularly the way she communicates Irena’s changing demeanor and resourcefulness.
The cast also includes Dougray Scott as Rugmer, Andrzej Seweryn as Schultz, and Maciej Nawrocki as Rokita.
A WWII Drama That Finds Tension in the Details
Irena’s Vow is not a battlefield movie. Its tension comes from the possibility of discovery.
Irena and the people she protects are forced to live with the knowledge that the safest hiding place they can find is also extraordinarily dangerous. German officers are nearby, and the villa itself is under Nazi control.
That gives the film a thriller-like quality without requiring conventional war-movie action. The threat is present in everyday situations: who enters the house, what someone notices, what Irena says, and whether a secret can remain a secret.
The film also benefits from knowing when to hold back. The subject matter could easily have been treated as a sweeping, highly sentimental Holocaust drama, but Irena’s Vow largely keeps its focus on Irena’s choices and the immediate danger facing the people she is trying to save.
That restraint has not made the movie universally acclaimed. Some reviews have argued that the film’s portrayal of Irena could have been more complex, while others have found its treatment of the historical material somewhat conventional. The Guardian, for example, described the drama as too tactful in places when confronting the horrors of Nazism.
Still, the film’s central story and Nélisse’s performance have connected with many critics, reflected in its current 86% Tomatometer score.

The official trailer was released by Quiver Distribution ahead of the film’s theatrical release and introduces Sophie Nélisse as Irena Gut Opdyke, with Dougray Scott also featured.
Why Irena’s Vow Stands Out on Netflix
There is no shortage of major World War II dramas. Schindler’s List, The Pianist, Saving Private Ryan and Band of Brothers have become enduring reference points for the genre, while newer films continue to bring lesser-known wartime experiences to the screen.
Irena’s Vow belongs to that latter group.
Its most striking element is the sheer improbability of Irena’s situation. She was not a soldier commanding troops or a powerful official with the ability to change policy. She was a young woman operating within a system controlled by Nazi Germany, using whatever access and opportunities she had to help people in immediate danger.
The fact that the people she protected were hidden in a villa occupied by a German officer makes the story particularly difficult to believe at first. Yet that is precisely what gives the film its tension.
Rather than relying on a fictionalized battlefield scenario, Irena’s Vow builds its suspense around a real woman’s attempts to keep 12 people alive while living dangerously close to the people who could have killed them.
For viewers interested in WWII dramas based on true stories, the film offers a story that may be unfamiliar even to audiences who have seen many Holocaust and World War II movies.
Its historical foundation, Sophie Nélisse’s performance and the unusual circumstances surrounding Irena’s rescue efforts make Irena’s Vow a striking addition to Netflix’s current selection of WWII films.
