College friends Jenny and Shiva part ways due to a misunderstanding. Although they are in love and realize they cannot live without each other, their egos prevent them from uniting.

Starting as an extra, Sathya shrewdly paves his way up to stardom as a leading hero. His ever-increasing popularity also leads him to joining an upcoming political party.

Shiva Raman (Prashanth), an easy-going young man, comes to London in search of a job, but he loses all of his certificates. He finds Kathiravan (Pandiarajan) wandering in London aimlessly without a job. Now, they both need jobs and money. Kathir persuades Shiva to join a bank robbery planned by Bhaskharan (Manivannan). His stammering brother Natrajan (Mayilsamy) and Aishwarya (Mumtaj), who is the former’s lover, lands them in more trouble, as the robbery ends vainly. Aishwarya informs the police about the robbery and tells that the entire plan was hatched by Bhaskar. Bhaskar hides the money before getting arrested, and the place is known only to his lawyer Vedimuthu (Vadivelu). Aishwarya fakes to be in love with Vedimuthu to find where the money is hidden.
Meanwhile, to find a safe cover, Shiva and Kathir plan to imitate Saravanan, the grandson of a rich elderly couple: Shiva Kumar (Vijayakumar) and his wife Parvathi (Srividya). They have not seen their grandchild since his birth. Shiva and Kathir end up disguising Kadhir’s body and Shiva’s voice to make up for Saravanan in front of the blind couple. Ganesh (Delhi Ganesh), who knows Kathir before, makes several attempts to expose the truth to the couple, but all fails, due to Shiva and Kadhir’s luck. All of a sudden, Anjali (Ankitha) arrives in the disguise of Saravanan’s lover. She calls on all the relatives of Shiva Kumar and Parvathi. The relatives arrive in Shiva’s absence. Finding no way out, Kathir pretends to have fainted unconscious, and he gets admitted to the hospital. Shiva comes to his rescue, and says that he is Dr. Karthikeyan, a friend of Saravanan from America….

Ezhumalai (Arjun) leads a peaceful life as a dance master in the village. Anjali (Gajala) falls in love with him before learning he has a son and his wife Lakshmi (Simran) is dead. She wishes to marry him but faces competition from Lakshmi’s sister Sandhya (Mumtaj), who also wishes to wed him. Anjali is the daughter of Nagalingam (Ashish Vidyarthi), who is from a neighboring village. When she reveals this fact to Ezhumalai, she learns he and her father are sworn enemies, and her father killed Lakshmi.

Jayaram alias Jerry (Jithan Ramesh) is a man who takes risks and hates love. He is challenged by his friends to make three women love him. He makes a police inspector and his classmate Janaki (Shruthi Raj), an actress Janani (Mumtaj), and a police officer Jeeva (Meera Vasudevan) fall in love with him. Whether the three girls find out and whom he unites with forms the crux of the story.

Indu and Chandru (Rambha and Karthik) fall in love. Indu does the disappearing act and Chandru gets engaged to Rekha (Mumtaz). Indu re-appears after three years with a little girl, who she claims is Chandru’s daughter. Chandru vehemently denies it and finding Indu’s presence an embarrassment tries to ferret out the truth. After many scenes of forced comedy, we learn that the girl is the illegitimate daughter of Chandru’s much-married brother, who had seduced Indu’s sister. After his brother’s futile attempt to play the villain, Chandru latches on to Indu fast enough with no apology to Rekha. But it is not really Chandru’s fault. For Rekha had done the disappearing act from the scene early enough without any explanation either.
