A family is traveling to Mumbai for a wedding and they meet a self-proclaimed tantric named Daina who claims to have the power to relieve people of evil spirits. She tries to perform a ritual on the family, but it backfires and she becomes the one who is affected. The family then continues their journey and reaches Bharat Nagar, where they are greeted by the wedding party. Meanwhile, another group of people, Shaurya and Vivaan, are trying to gather four doppelgangers, including a character named Debu, to take them to a safe place called Veerlok. They use a device called the "Contact Machine" to try and communicate with Debu's spirit, but it doesn't work at first. Later, they try again and Debu's spirit finally responds. However, their plan is being monitored by a villainous character named Kaal, who plans to attack and destroy the doppelgangers once they are all gathered in one place.
