In the town of Chanderi, there is a widespread belief in the spirit of an angry woman known as Stree. During a four-day religious festival each year, she is said to stalk the men of the town, whispering their names and causing disappearances if they look back at her. To protect themselves, residents write “o stree kal aana” in blood on their doorways. Additionally, men are advised to avoid going out alone after 10 PM during the festival and to move in groups for safety. This practice reflects a societal parallel to the precautions typically advised to women for their own protection.

Vicky, a ladies’ tailor in Chanderi, encounters a mysterious girl, credited as Girl with No Name, during the annual pooja season and falls in love with her at first sight. She requests him to stitch a lehanga. However, her frequent disappearances and unusual shopping list—containing items like a lizard’s tail, white cat’s fur, Datura flowers, meat, and brandy—raise concerns for his friend Bittu, who suspects she might be Stree. This suspicion deepens after another friend, Janna, is kidnapped by Stree. Vicky also grows wary of the girl and confronts her, but she vanishes yet again.

Vicky, Bittu and Rudra Bhaiya, the town’s librarian and a paranologist, seek a way to save their friend Janna. They discover a partially torn book titled Chanderi Puran in Rudra’s library, which details Stree’s story and mentions an old fort. Vicky recognizes the fort from a date with the Girl with No Name. The trio visits the fort, believed to be Stree’s lair, to find Janna. Stree drives away Bittu and Rudra and nearly attacks Vicky but refrains upon sensing love and respect in his eyes. She is then repelled by the girl’s spell.
