Netflix’s 86%-Rated WWII Drama Irena’s Vow Tells a Remarkable True Story of Courage

A 19-year-old woman secretly hiding Jewish people in the basement of a Nazi officer’s home sounds like the premise of a wartime thriller. In Irena’s Vow, however, the danger came from a real decision made by Irena Gut Opdyke during the German occupation of Poland.

The 2023 historical drama has found a new audience on Netflix UK after being added to the service on August 31, 2026.

Directed by Louise Archambault and written by Dan Gordon, the film stars Sophie Nélisse as Irena, with Dougray Scott and Andrzej Seweryn in major roles. Rotten Tomatoes currently lists the film at 86% from 36 critics, with an 83% audience score.

Those numbers are notable, but the real reason the film stays with viewers is the extraordinary story at its center.

A 19-Year-Old Makes an Impossible Choice

Irena Gut is only 19 when the events of the film unfold. Working under the German occupation, she is eventually placed in charge of a villa belonging to Major Rügemer, a German officer played by Dougray Scott.

Her position gives her something that many others do not have: access.

When she learns that the Jewish ghetto is about to be liquidated, she decides to use that access to help Jewish workers who would otherwise face almost certain danger.

She hides twelve Jewish people in the basement of the German commandant’s house.

The decision changes everything.

Irena still has to perform her duties and maintain the appearance of an ordinary housekeeper. At the same time, she must make sure that the people hidden beneath the house remain undiscovered.

Nazi officers and guests come and go. Parties are held inside the villa. A single suspicious sound or careless mistake could expose the entire operation.

The tension comes from that constant possibility of discovery. There is no need for a chase or a battle to create fear. The danger is present in ordinary conversations, footsteps and unexpected visitors.

As the film’s premise makes clear, Irena’s concealment effort continues for an extended period while she tries to protect the people depending on her. Rotten Tomatoes describes the story as spanning the final two years of the German occupation, with Irena relying on wit, humor and courage to keep the group safe.

The Extraordinary Part Is That It Really Happened

The story behind Irena’s Vow comes from the life of Irene Gut Opdyke, whose wartime experiences were documented in her memoir In My Hands: Memories of a Holocaust Rescuer.

The book was published by Knopf in 1999 and written with Jennifer Armstrong. It recounts how Gut, a young Polish Catholic and nursing student, gradually became involved in helping Jews persecuted by the Nazis.

Her resistance began with relatively small acts. She secretly supplied food, passed information to people in the ghetto and helped others evade German persecution. Eventually, she was able to hide twelve Jews in the basement of a Nazi major’s home while working there as a housekeeper.

That history gives the film an unusual emotional weight.

Irena is not presented as someone who has all the answers or knows how events will unfold. She is a young woman trying to survive under an occupation while making decisions that could have fatal consequences.

Her courage comes from continuing to act despite the danger.

Sophie Nélisse Anchors the Film

Sophie Nélisse carries much of the drama as Irena Gut.

Her performance has been singled out by critics for its restraint and emotional detail. RogerEbert.com’s Christy Lemire praised Nélisse’s ability to communicate through her expressions and shifts in demeanor, particularly as Irena learns to adapt to an increasingly dangerous environment.

The film follows Irena as she develops from an idealistic young woman into someone increasingly resourceful and capable of making difficult choices.

That evolution is central to the story. She has to understand the people around her, anticipate danger and maintain different versions of herself depending on who is watching.

For Nélisse, much of the challenge lies in communicating that fear without turning Irena into a conventional action hero.

The result is a performance built around observation, restraint and the pressure of knowing that one mistake could endanger twelve other lives.

Dougray Scott Brings Another Layer to the Story

Dougray Scott plays Major Rügemer, the German officer whose villa becomes the unlikely refuge for the people Irena is trying to save.

That setting creates one of the film’s most disturbing contrasts.

The house is part of the machinery of the occupying regime, yet underneath it, Irena is secretly protecting people from that same regime.

Rügemer also becomes one of the film’s more complicated figures.

Reviews have noted the tension between Irena and the Major as their relationship develops. RogerEbert.com’s review describes Scott’s performance as increasingly layered as Rügemer reveals more of his insecurities.

The British Film Institute’s review similarly identifies Rügemer as one of the film’s central mysteries and notes the unusual atmosphere created by having the hidden Jewish workers exist beneath the home of the very system persecuting them.

That makes even seemingly ordinary interactions carry a second meaning.

A conversation in the house can have consequences far beyond what is said aloud.

A Story Adapted More Than Once

Irena’s Vow did not go directly from Irena Gut Opdyke’s memoir to the screen.

Her story was first told in In My Hands, published in 1999. The story was later adapted for the stage, with Dan Gordon writing the screenplay for the feature film from his own stage play.

Louise Archambault directed the film, while Gordon wrote the screenplay.

The finished movie runs for about two hours and one minute and is classified as a drama, war and biographical film.

The film’s straightforward approach has divided critics in some respects. The British Film Institute described it as a plainly told account of extraordinary wartime courage, while also arguing that the story is sometimes simplified.

Other reviews have praised the performances and the value of bringing Gut’s story to a wider audience, even while questioning some of the screenplay’s choices.

That distinction is worth remembering when looking at the film’s strong Rotten Tomatoes score. The 86% figure reflects a broad critical response, but individual reviewers have not all agreed on how successfully the movie handles its material.

Why the Story Still Feels So Powerful

There have been countless films about World War II and the Holocaust.

What makes Irena’s Vow different is the scale of its story. Rather than focusing on armies, major battles or famous historical figures, it follows one young woman whose choices are made inside a single dangerous household.

The film’s tension comes from how little room Irena has for error.

She has to keep working for a Nazi officer while secretly protecting Jewish people from persecution. The people she is hiding are close enough to danger that even everyday household events can become threatening.

The Guardian described the film as a dramatized retelling of Gut’s efforts to hide twelve Jews in the basement of the home of the Nazi officer for whom she worked.

The BFI likewise notes that Gut was 19 and spent much of the war hiding twelve Jewish people in the cellar of her Wehrmacht employer’s home.

That historical reality is perhaps the film’s most striking element.

Irena did not know how her story would end when she began taking these risks. She had to make each decision without knowing whether the next visitor, inspection or conversation would expose what she had done.

A Hidden WWII Story Finds a New Audience

The arrival of Irena’s Vow on Netflix UK has given the film another opportunity to reach viewers who may never have heard of Irena Gut Opdyke.

Netflix’s UK listing describes it as the story of a Polish woman working as a housekeeper for a Nazi officer who risks her life to hide Jews in his villa during World War II.

The film was added to Netflix UK on August 31, 2026.

For someone browsing the service, it can easily appear to be another historical war drama. The story becomes much more affecting once the historical basis is understood.

The twelve people hidden beneath the house were not fictional characters invented to create suspense. The central act of rescue came from a real woman’s wartime experience, later recorded in her memoir.

That context also explains why the film can feel so intimate. The danger is concentrated around a handful of people and one secret that must be protected at almost any cost.

The Film’s Strongest Asset Is Its Central Story

Not every critic has found the filmmaking equally convincing.

The Guardian criticized the movie for presenting the Holocaust experience in a relatively sanitized way and for making Irena seem overly saintly.

The BFI similarly suggested that the film oversimplifies aspects of Gut’s story, even while emphasizing that her remarkable experience deserves to be told.

Yet even those reservations point toward the same underlying fact: Irena Gut Opdyke’s story is powerful enough to command attention.

Her memoir provides a record of a young Polish woman who gradually moved from small acts of resistance to the extraordinary decision to hide twelve Jews in the basement of a German officer’s home.

That history gives Irena’s Vow its lasting significance.

The film is ultimately about fear as much as courage. Irena has every reason to be afraid, and the danger surrounding her never disappears. What distinguishes her is the willingness to continue helping others despite knowing what discovery could mean.

For viewers encountering her story for the first time, that may be the most memorable part of Irena’s Vow: the knowledge that the woman at its center was not a fictional hero designed for a screenplay.

She was a real young woman who made a series of extraordinarily dangerous choices during one of the darkest periods in modern history.
