Set in Bengal Presidency during 1881, the film shows a 5-year old Bulbbul getting married to few decades older Indranil who has a younger twin, Mahendra (who is mentally challenged), and the youngest Satya (who is closer to her age and whom she assumes is her husband). Twenty years later, we see Satya returning from London after studying law; Mahendra has died under mysterious circumstances and it has been five years since Indranil left home permanently. The young child bride, Bulbbul, is the thakurain of the ancestral mansion. Satya visits his elder widowed bhaabi who tells him some chudail killed her husband because she found reversed foot prints leading away from his body. More stories of men being killed in the village by a witch begin to capture the interest of Satya, enamored by the confident and self-assured Bulbbul who is shown to be an emotional wreck and docile when Satya was leaving for London.

In flashback throughout the movie, Bulbbul and Satya are always close being...
