Six students visit Sonamukhi for research, but soon uncover the village is haunted by Nishi's curse.
After a friend's death, they discover singing in the village is deadly, as Nishi had killed six musicians before.
One constable is dead. Five friends trapped in the night. And a room that holds their worst nightmare.
Nishi possesses Anirban, a mysterious old woman speaks to them, and Titli receives strange letters.
When Titli thinks of the village, the silence feels heavier as it still guards a story she was never meant to uncover.
A buried sin resurfaces. Will Nishi find peace, will her song meet its end, or will the curse remain unbroken?
