Who Is Melis Sezen? Not a Stranger Actress on Netflix

Melis Sezen becomes the biggest mystery of Netflix’s Turkish series with Not a Stranger: what is Nazlı hiding?

Melis Sezen is once again in the spotlight with Not a Stranger (Seni Tanıyorum), the new Turkish mystery and suspense series arriving on Netflix this September 17, 2026. The actress plays Nazlı, a nanny who seems to enter a family's life to solve their problems, but whose presence ends up becoming the greatest source of unease.The premise seems simple: Funda wants to get her artistic career back after becoming a mother and needs help taking care of her son. When Nazlı appears, everything seems to fall into place. The problem is that the new nanny is hiding a mystery that threatens to change the lives of Funda and her husband, İlker, forever.Netflix describes the production as a psychological Turkish drama with suspense, featuring secrets, mind games, and tension that builds around the arrival of a seemingly trustworthy person into the family unit.

Who is Nazlı, Melis Sezen’s character in Not a Stranger?

Nazlı is the new nanny who enters Funda and İlker's home. At first, her arrival represents exactly what Funda needs: someone who can help her with motherhood while she tries to make up for lost time and refocus on her career as a painter.However, Nazlı quickly raises suspicions. Her personality, her behavior, and what she seems to be hiding turn an everyday situation into an unsettling game of secrets.

A nanny who changes the family’s rules

The character's real appeal lies in the fact that Nazlı doesn't simply appear as a secondary figure within the story. Her arrival shifts the family's balance and puts Funda and İlker in a situation that increasingly slips out of their control.The series plays precisely with that doubt: who is Nazlı really, and what is she after by entering this family's life?That mystery is one of the main driving forces of Not a Stranger and also explains why Melis Sezen has become one of the faces generating the most curiosity ahead of the premiere.

Funda and İlker: the couple whose lives change with Nazlı’s arrival

The story also revolves around Funda, played by Elçin Sangu, and İlker, played by Ozan Dolunay. After becoming a mother, Funda wants to get her career as an artist back and return to painting.Nazlı's arrival seems to offer the perfect solution. But the calm doesn't last long.

Funda wants to return to art, but something starts to break her balance

Funda finds herself at a particularly vulnerable moment: she's trying to balance motherhood with the desire to reclaim a part of her identity that she had set aside.Nazlı's arrival should make that process easier. Instead, the new nanny becomes an increasingly unsettling presence.

İlker also gets caught up in the mystery

İlker shares with Funda the consequences of Nazlı's arrival. What begins as a seemingly practical family decision ends up affecting the couple's stability. So the mystery isn't limited to discovering what Nazlı is hiding: it also raises the question of just how much her presence can transform the relationship between Funda and İlker.

Why is Melis Sezen one of Not a Stranger's biggest bets?

Casting Sezen to play Nazlı is especially significant because the character needs to maintain a dual reading for much of the story.On one hand, Nazlı must seem like someone capable of earning the trust of a family that desperately needs help. On the other, the series constantly needs to create the feeling that there's something we're not seeing.That contrast makes Melis Sezen a fundamental piece of the mystery. Her character doesn't work only because of what she does, but also because of the questions she raises.

The big mystery: what is Nazlı hiding?

The question that will likely follow viewers through the first episodes is simple: what is Nazlı hiding?The answer is part of the series' central mystery, and revealing it early would ruin one of the elements Netflix uses as its main narrative hook.That's why, rather than presenting Nazlı as a villain or attributing specific intentions to her before the premiere, it's more interesting to follow the clues the story itself will leave behind.

When does Not a Stranger premiere on Netflix?

Not a Stranger premieres on Netflix on September 17, 2026. The production is a Turkish series created by Tuğba Doğan, with Mert Baykal as director.The main cast includes Elçin Sangu as Funda, Melis Sezen as Nazlı, and Ozan Dolunay as İlker.

What can we expect from Not a Stranger?

• A mystery centered on a family and their new nanny.
• A seemingly trustworthy protagonist who raises suspicions.
• Secrets that threaten Funda and İlker's stability.
• A psychological suspense story set in a domestic environment.
• A new Turkish Netflix production starring Melis Sezen.

With these ingredients, Not a Stranger bets on a type of suspense that doesn't need grand settings to create tension: it's enough that the person who enters the home isn't who she claims to be.
