Between Mahalaya and Vijayadashami, in north Kolkata, the aristocratic Banedi jewellers Basak family faces a season that tests loyalty, tradition, and the thin line between aid and temptation. Durga, Sohini Sarkar enters the house as a nurse to care for the eldest Basak, a role that pulls her into the daily rhythms and rituals of the family while the festive air swells with ancient expectations. The atmosphere is steeped in customs, whispered judgments, and the heavy weight of keeping a legacy intact.
Yet Durga's arrival unsettles more than the schedule. She is revealed as a thief when she is confronted by Manashi, Tanushree Chakraborty, the younger daughter-in-law who sees beyond appearances. Manashi’s compassion shines through as she pleads for mercy and persuades the others to refuse a harsh punishment, urging them to give Durga a second chance and a place within the household’s fragile harmony.
Over time, Durga begins to blend in, quietly earning the family’s trust and becoming virtually a member of the domestic sphere. The plan behind her appearance threads through the backdrop of the house, coming from Madhav, Anirban Bhattacharya, her husband and a dacoit with a dangerous agenda. The two forge a risky alliance, plotting to raid the Basak home during the festive crescendo of Dashami, riding the tension between fear and desire for redemption.
Durga’s loyalties tilt at a crucial moment. She alerts the police ahead of the planned raid, foiling the criminals and shifting the balance of power within the household. When the gang is captured, she herself is detained as well. The truth about her life as Chaina—the informer for the thieves and the one guilty of three thefts—emerges, complicating the Basak family’s sense of mercy, duty, and the possibility of understanding the person behind the double life. Throughout, the family’s stance remains, at times stern, at others forgiving, reflecting the complex weave of trust and survival.
In the end, Maa Durga’s symbolic departure mirrors a quiet, hopeful turn. Durga/Chaina leaves with a sense that time may bring a return—an opportunity for reconciliation and homecoming for everyone involved. The film closes on a note of cautious optimism, suggesting that the paths of duty, guilt, and redemption can cross again when the seasons align, and that even a contested past can be folded into a future where belonging is reimagined.
