After her marriage with the almost fifty years aged guy Sahay, the twenty four years aged Mayuri thought her challenge was only to make her step-children Sameera and Pradeep amicable and friendly with her. The two things which she did not expect to happen but have taken place were; her feeling love towards her husband abundantly and her overwhelming grateful feeling and pity towards the insane first wife of her husband Niyoja. When her step-daughter Sameera also started behaving mad just like her mother while Mayuri was trying to find ways to make Niyoja sane, Mayuri’s belief that the bad angel Amsara was behind the misfortune of her husband has been strengthened even more. Against the strong confirmation of the psychiatrist Devayani who was the sister of her husband and treating Sameera and her mother that there is never any paranormal, not to say a bad angel like Amsara, Mayuri started trying to find a paranormal solution to the problem. Her going to Obbera, a small village in the very corner of the country where adoring bad angels is the main activity of the villagers; was only to follow a paranormal solution suggested by Palamita who knew about Amsara to cure her step-daughter. Whether offering herself at Amsara has become successful and cured her step-daughter or not is the main story of this novel.
Along with this main story, the romance and love of her step-children, her own sister and other characters linked with these characters make the whole story of this novel.
