Gautam Prabhakar (Vijay) is searching for Gayathri (Kaveri) who was an innocent girl that kept coming to him for help of many sorts. He comes across Surya and Chandra (Charlie and Dhamu) and Hema (Shalini). They try to cheat Gautam (like many others) but fail in doing so. Hema finally realizes that he may actually have a disease. She and her father, Dr. Rajsekhar (Raghuvaran) try to help him out. After examing his's subconscious mind, Raghuvaran finds out that he's suffering from split personality and has forgotten a lot of things.
