Abhi (Jeet) is a funloving and extremely popular boy from Phoolbari, a small township in North Bengal. His father Indranath (Biswajit Chakraborty) is a highly respected man in Phoolbari. Agnidev Roy (Bharat Kaul), a dreaded mafia from Kolkata, sends his daughter Shruti (Srabanti) to Phoolbari on a vacation. Binay (Supriyo Dutta) an old aide of Agnidev requests Abhi to receive Shruti at the railway station. Abhi takes an instant liking for Shruti the moment he sets his eyes on her at the railway station. Gradually, Shruti starts to enjoy the company of Abhi and his friends and the fondness between Abhi and Shruti grows. One day, Abhi finds out that Shruti is suffering from 'post traumatic event disorder', since the time she met with a car accident recently. She has no memory of the last three years. When Abhi takes her to a doctor at Phoolbari, the doctor states that Shruti can be cured, but she might not remember anything of her visit to Phoolbari, her friends or even Abhi. Upon hearing this Shruti is disheartened and she persuades Abhi to promise her that he will never leave her, even if she is cured and is not able to remember him. Agnidev Roy gets furious when he learns of Shruti's relationship with Abhi and reaches Phoolbari with his goons. The people of Phoolbari oppose Agnidev. Looking at this situation Agnidev agrees to the engagement of Shruti and Abhi, but cunningly thrashes Abhi at a remote place and takes his daughter back to Kolkata. When Abhi goes to meet Shruti, she fails to recognize him. She is now cured and is set off to be engaged with someone else. But Abhi, had given a word to his beloved that he would never leave her. How he tries relentlessly to convince her and what happens with Shruti forms the rest of the story.
