Aaditi and Aditya are a married couple with two children. They are wealthy and live in a mansion. Their idyllic life is shattered with the arrival of Sonia, who has an affair with Aditya. Eventually, Aditya leaves his family for Sonia, leaving the wife and two kids alone. When it is found out that Sonia is barren, Aditya demands custody of his children from Shivani and approaches the courts for a custody battle. Eventually, the courts ruled against Shivani and awarded custody to Aditya and Sonia. The movie changes its ambiance from the family dispute to one of suspense and horror shortly after.
