Netflix’s ‘Not a Stranger’ Release Date and Time, Trailer, Plot, and Cast Explained

‘Not a Stranger’ is set to arrive on Netflix this week, and the psychological drama has already generated buzz thanks to an unsettling first trailer centered on a nanny with a hidden agenda. The Turkish series leans into slow burn suspense rather than jump scares, positioning itself as a domestic thriller about trust, motherhood, and the secrets a stranger can bring into a family’s home.

With the premiere date now confirmed and a full cast list attached, viewers have a clearer picture of what to expect. Here is what has been revealed so far about the story, the people bringing it to life, and when it will be available to stream.

‘Not a Stranger’ Release Date

‘Not a Stranger,’ known under its original Turkish title Seni Tanıyorum, is scheduled to premiere on Netflix on September 17. The series was created by Tuğba Doğan, who blends psychological suspense with family drama in the story. Netflix’s own listing for the show confirms the September date alongside a description that frames the series around a mother caught between her career and her newborn’s care.

The show’s arrival was also folded into Netflix’s broader September lineup. According to a rundown of new Netflix titles, September 17 brings ‘The Fixers,’ ‘Monster: The Lizzie Borden Story,’ ‘Not a Stranger,’ ‘Plastic Beauty,’ and ‘Stranger Things: Tales From ’85: Season 2’ all to the platform on the same day. That crowded release slate places ‘Not a Stranger’ alongside several higher profile titles, which may affect how quickly it climbs Netflix’s daily charts in its opening days.

‘Not a Stranger’ Trailer Details

The official trailer leans heavily into dread rather than exposition, building tension through small, unsettling moments rather than overt violence. The trailer opens with Funda, a loving mother who is deeply attached to her newborn daughter, and shows her struggling to trust anyone to look after the child. During a swimming session, Nazlı asks who Funda would trust to watch her little princess, a moment that leaves Funda visibly hesitant.

As the preview continues, the nanny’s behavior grows increasingly troubling. The trailer shows Nazlı coercing the young child to call her Mom, which prompts İlker to suspect that something is seriously wrong, setting the stage for a far more unsettling conflict as Nazlı appears to want the baby entirely for herself. The YouTube release of the trailer carries its own blunt tagline. The trailer’s closing line states simply that she let her in, and that was the first mistake, confirming the show is only on Netflix starting September 17th.

The marketing approach mirrors a broader trend in psychological thrillers that withhold the antagonist’s full motivations until deep into the season, relying on audience unease rather than explicit reveals to sustain interest between episodes.

‘Not a Stranger’ Plot Summary

The series follows Funda, an artist and new mother who is trying to reclaim the career she paused after giving birth. The official synopsis explains that after giving birth, Funda wants to return to painting, the career she had paused, and finally finds the nanny she has been looking for. That decision sets the entire story in motion. Nanny Nazlı’s mystery and unsettling nature will change Funda and her husband İlker’s lives forever, according to the synopsis.

Netflix’s own platform description reinforces the central conflict at the heart of the show. The listing states that caught between motherhood and her art career, Funda is relieved to get some help, but shrouded in secrets, her new nanny might not be all she seems. The series is tagged internally by Netflix under genres including psychological, suspenseful, slow burn, and mind game, signaling a deliberate pace built around tension rather than fast twists.

A key thread involves Nazlı’s own backstory, which the trailer suggests is tied to her inability to have children. Nazlı can’t have children, which eventually unveils her much darker side as the story progresses. That detail positions her less as a straightforward villain and more as a character whose desperation drives the season’s central threat, a common device in domestic thrillers that ask audiences to understand a character’s motivations even as they condemn her actions.

‘Not a Stranger’ Cast and Crew

The series is led by a trio of established Turkish actors. Elçin Sangu stars as Funda, while Ozan Dolunay plays İlker, with Melis Sezen also part of the core cast. Behind the camera, the show comes from a director and writer with distinct roles on the project. Mert Baykal directed the series, which was created and written by Tuğba Doğan, with Bombon Studios producing.

The supporting ensemble rounds out the family drama with several additional performers. The series also stars Cemal Hünal, Efe Taşdelen, Murat Garipağaoğlu, Mine Teber, Nergis Öztürk, Arbil Tabur, Esra Şahin, and Ada and Arya Özdemir. Netflix’s own credits list largely mirrors this lineup, confirming the same core group of actors across its official trailer page.

Given that ‘Not a Stranger’ arrives from a team with direct experience in tightly plotted Turkish dramas, expectations are that the series will lean on performance and atmosphere over spectacle. Viewers who gravitate toward slow burn domestic thrillers will likely find familiar rhythms here, even as the specific setup involving a nanny’s hidden agenda gives the story its own identity within a crowded genre.

Once Nazlı’s true intentions come into full view, viewers may find themselves debating just how far they would go to protect a child from a threat hiding in plain sight within their own home.
