‘Must-See’ WWII Film You May Have Never Heard Of Is Now Streaming on Netflix
A little-known World War II drama is gaining attention on Netflix, with viewers praising its powerful true story, emotional performances and gripping suspense.
Irena’s Vow (2023) tells the remarkable story of Polish nurse Irena Gut Opdyke, played by Sophie Nélisse, whose courage placed her life in danger as she secretly protected a group of Jews during the Holocaust.

Forced to work as a housekeeper for a high-ranking Nazi officer, portrayed by Dougray Scott, Irena takes an extraordinary risk by hiding Jewish people inside his home.
Directed by Louise Archambault and written by Dan Gordon, the film is based on Opdyke’s 1999 book In My Hands. Gordon had previously adapted the story into a Broadway play before bringing it to the screen.
Now that the film has been added to Netflix in the UK, viewers are discovering a wartime story that has earned a strong response from critics and audiences alike.
A True Story of Courage and Survival

At the center of Irena’s Vow is Irena Gut Opdyke, whose experiences during World War II form the foundation of the film.
Her position working for a powerful Nazi officer gives her access to his home, but it also creates a dangerous opportunity. She secretly hides a group of Jews there, knowing that discovery could have devastating consequences.
The film focuses on the tension surrounding that decision and the extraordinary risks involved in keeping the people she is protecting hidden.
Rather than presenting the story simply as a historical account, Irena’s Vow places its emotional weight on the people caught inside an increasingly dangerous situation.
Viewers Praise the Performances

The film has attracted enthusiastic reactions on Rotten Tomatoes, where it currently holds an 86% Tomatometer score.
One viewer praised the cast for delivering “phenomenal performances,” while particularly highlighting Nélisse’s portrayal of Irena.
Another audience member described the film as a “must-see,” praising Nélisse and the rest of the cast while calling the story full of drama and suspense.
Other viewers were equally moved by the film’s conclusion. One said they were left crying at the end, describing it as a “wonderful ending.”
Another praised the movie as an “excellent true story” that was “very well told by a superb cast.”
The response suggests that the film’s emotional impact is one of its strongest qualities, particularly for viewers drawn to historical dramas based on real events.
Sophie Nélisse and Dougray Scott Lead the Cast

Sophie Nélisse takes on the central role of Irena Gut Opdyke, carrying much of the film through her performance.
One Rotten Tomatoes reviewer said the lead character was exceptionally well cast and suggested that Nélisse conveyed much of Irena’s story through her expression alone.
Dougray Scott plays the high-ranking Nazi officer for whom Irena is forced to work.
One viewer specifically noted Scott’s performance, recalling his earlier appearance in Mission: Impossible 2.
Together, the performances help drive a story in which fear, secrecy and moral courage remain at the center.
A Story That Began With Irena’s Own Words
The film’s journey to the screen began with Opdyke herself.
Her 1999 book, In My Hands, provided the foundation for Dan Gordon’s earlier Broadway play. Gordon then adapted the story for the 2023 film, directed by Louise Archambault.
That connection to Opdyke’s own account has also been highlighted by viewers.
One Rotten Tomatoes user said they appreciated discovering a story they had never heard of and particularly liked that it was based on true events.
For audiences unfamiliar with Irena Gut Opdyke’s story, the film therefore offers both a historical drama and an introduction to an extraordinary chapter of World War II history.

Irena’s Vow was recently added to Netflix in the UK, giving the film a new opportunity to reach viewers who may have previously overlooked it.
