Shiv Kakkar is a banker from Amritsar who gets a lucrative opportunity to work in Budapest. He is a fun-loving playboy back home and continues this behaviour in Budapest. Saira Singh is a young woman haunted by mysterious nightmares of drowning to death. She lives by herself in Budapest and works as a chocolatier. Shiv happens to stumble upon Saira’s shop while on a date with a woman, but finds himself deeply attracted to Saira. Shocked by the weird connection she feels with Shiv, Saira initially rejects his advances, but eventually succumbs. The next day, Saira reveals that she has never felt such a connection before but is in a mess as she has a boyfriend. Unwilling to let go of their connection, Shiv interrupts Saira’s date with her boyfriend Manav and shows her that she would rather be with him than with her boyfriend. Manav breaks up with her, and Shiv and Sairah start spending time together, growing close. One night, they go to a club where Saira tearfully reveals to Shiv that she has a fear of water because her parents drowned after a car accident when she was two years old. Shiv reveals to Saira that he has to leave for a business trip for a week. They decide to see how they feel after a week's separation. During Shiv's absence, Saira gets to know Zakir and confides in him about her nightmares. During one of their dinners, Zakir drugs Saira and kidnaps her. Sairah wakes up and finds herself trapped in Zakir's isolated mansion on an island off the coast. She demands him to let her go, but he refuses, saying that he spent his whole life looking for her. He explains that he was madly in love with her in a previous life, but his love remained unrequited. He refuses to let go of her again. When she does not believe him, he shows her a collection of uncannily accurate paintings he made of her at various ages and says she will find the explanation for her nightmares. Thinking he is crazy, she attempts to escape but ends up falling into the ocean, which triggers the memories of her previous life. Eight hundred years ago, Saira was warrior princess Saiba. She had a childhood best friend, Qaabir (present day Zakir), a fellow warrior from her tribe who was in love with her. Their kingdom was threatened by the Muraakis, led by a wise, old Rajput ruler Muwwaqqil. Qaabir is severely wounded by the fierce warrior Jilaan (present day Shiv), who gives Qaabir an ultimatum to surrender. Saiba challenges Jilaan, and they find themselves attracted to each other. Saiba accepts defeat, surrendering the kingdom to the Muraakis and herself to Jilaan. Qaabir attempts to take Saiba back, but she reveals that she and Jilaan are in love. On their wedding night, a comet falls, and Muwwaqqil realizes that this will be a fateful night. Qaabir ambushes Jilaan and Saiba, and murders Jilaan by wounding him and throws him in the ocean. Saiba jumps into the ocean to save him, but to no avail. Heartbroken on seeing Jilaan die, Saiba decides to drown too. On seeing Saiba dead, Qaabir slits his own throat, killing himself. Muwwaqqil forebodes that these events will repeat. This time around, when Shiv shows up, Saira decides to fight back against Zakir. When their previous lives' events repeat, Zakir throwing Shiv into the ocean, Shiv drags Zakir down with him, and Zakir dies. Saira jumps into the water and is able to save Shiv. They both swim to shore, only to find the boat on fire and Radha nowhere to be seen. Shiv looks for him in one spot but a little later, he (Radha) is shown holding onto a barrel he didn't explode with Zakir's gun to kill his henchmen
