On 4 January 2016. Rehaan (Gaurav Arora) and Shaina (Kriti Kharbanda) return to Romania after a few years of their marriage. Apparently, they had lived there when they were unmarried. But when Rehaan got an offer as a Venture Capitalist for the East European Finance Company, Shaina was insistent that he take up the job. Rehaan was reluctant, since he had a secret to hide. On the very first day, while unpacking her luggage, Shaina experiences paranormal activities. Rehaan refuses to believe her. A month later, while on a business trip, Rehaan receives a frantic call from Shaina requesting for help. She is found holed up in a telephone booth in a rural area. Apparently, she had gone there to visit a clairvoyant. And hence, the narrative juggles back and forth as to what plagues them and what leads her to the clairvoyant. The local priest tries to perform an exorcism on Shaina but fails as the spirit knows the priest's past and uses it against him to send him away running. A blind Indian student, Trilok who is studying Psychometry in Romania then enters the scene and then, enters Aditya Shrivastava (Emraan Hashmi), to rescue his lady love from the evil spirit. Aditya has some strange premonition about all the events taking place in Shaina's life. He offers to help her to fight the spirit and free her from all the pain she is going through. Although, Shaina doesn't believe him at first, certain series of events make her believe that the spirit has something to do with her husband Rehaan. She finds out that he is keeping a certain secret which has now become the cause of the haunting. Eventually, Rehaan confesses that he had murdered Aditya and the latter's ghost is seeking revenge. Four years ago, just before Shaina's marriage, Aditya had called Rehaan revealing himself as her ex-boyfriend. Aditya had invited Rehaan to his residence and had blackmailed him for insider trading. Aditya told Rehaan he was willing to drop the charges if Rehaan broke off his engagement to Shaina, so that Aditya can rekindle his relationship with her. Rehaan tried to quietly leave but Aditya showed him photos of his intimate moments with Shaina and began to taunt him. Enraged, Rehaan had struck a fatal blow to Aditya on the head, killing him. As Aditya lay dying, he vowed vengeance. The spirit of Aditya then takes complete possession of Shaina's body. To save Shaina from the evil spirit of Aditya, Trilok recites Gajendra moksh stotra, an enchantation believed to be more powerful than Lord Vishnu's mantra. By reciting this mantra, Aditya's evil spirit will have to leave Shaina's body, but there's a condition, that the mantra was to be recited without a break. Though Aditya's spirit stops Trilok and Rehaan from completing the mantra, Rehaan saves Shaina from Aditya. The movie ends with Rehaan and Shaina sitting by the lakeside talking about how there was a lot of ice around their house when they had first arrived but now all of the ice had melted, symbolizing the increased closeness between the couple
