While drunk he unknowingly tells Mark (Rajendran), who is a hitman, to kill his competitor at work, his loan shark, and Deepika. When he wakes the following morning, he finds that his colleague and his loan shark are dead, and a call from Mark telling Saravanan that he has done what he has asked.

One prospective girl’s father Sathyamoorthy (Sampath Raj) insults Rajini because of this. As fate would have it, Rajini ends up falling in love with Sathyamoorthy’s daughter Vandhana (Sayyeshaa), but she is unaware of his forgetfulness. How long can he continue with this facade, especially with Ajay (Lijeesh), a cop who wants to marry Vandhana and is trying to expose him?

His stammering brother Natrajan (Mayilsamy) and Aishwarya (Mumtaj), who is the former’s lover, lands them in more trouble, as the robbery ends vainly.

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….
