Set in the 19th century Bengal Presidency, Bulbbul is married off to the elder lord Indranil at age five. She grows up with his youngest brother Satya, sharing tales of a demon woman (chudail). Twenty years later, Satya returns from London to find Mahender, Indranil’s twin, dead in a chudail attack, his widow Binodini living in an outhouse, and Bulbbul now managing the estate. Village doctor Sudip’s frequent visits to treat Bulbbul’s feet spark jealousy in Satya. When a man is killed during a hunt, blamed on the chudail, Satya suspects Sudip. The story weaves folklore, betrayal, and female empowerment.
