Not a Stranger premieres on Netflix on September 17, 2026, with a story about a mother, her career, and a new nanny whose secrets begin to disturb the family. Netflix says Funda is caught between motherhood and her art career when the nanny arrives.
The setup is built around domestic trust rather than an open investigation. The nanny is meant to provide help, but her hidden past threatens the balance between Funda and her husband.
