Somasundaram(S. Balachander), a wealthy businessman, summons his office staff members and bids farewell to Aanandan, Mani, Sampath(Sadan), and Prabhakar as he plans to go to Singapore from Chennai shortly. But Somasundaram refuses to disclose the exact reason for the journey and said it would take about 10 days. He met his business partner, Jagadish(V. S. Raghavan), on his way to the airport and said goodbye to him too. It is revealed to us that Jagadish is related to a murder case in Singapore a few years ago, before joining as a partner at Somasundaram's business. Jagadish sensing this, Somasundaram's Singapore journey may lead to the end of his business partnership, as the murder issue would come to light. So, as a team, Mani, Sampath, and Prabhakar join hands with Jagadish to kill Somasundaram. Prabhakar plants a powerful bomb and fixes it inside a walking doll. They plan to give the doll to Somasundaram at the airport and ask him to present it to the particular address in Singapore. The address card is pasted on the stomach of the doll. So when Somasundaram pulls out the card, it triggers the lever, and the bomb will explode within seconds.
The trio goes to the airport in a hurry, and their car breaks down in the middle. So Mani and Sampath hire a taxi and go to the airport. Due to a misunderstanding, they left the doll in the taxi. When Prabhakar arrives at the airport and hears this out, he spills the secret without noticing Aanandan is nearby. A kind-hearted Aanandan goes in search of that taxi to find the bomb doll with Prabhakar's sister, Mallika(L. Vijayalakshmi).
The doll in the taxi goes to a family, an orphanage, a blind beggar, and finally to a doll shop. Meanwhile, Jagadish's group also searches for that taxi to retrieve the doll, but it goes in vain. So they abducted Aanand, as he knows their plan and would go to the police. Prabhakar says that if there were more time for flight departure, he would make another bomb doll similar to this, as it requires just half an hour. At the time the doorbell rings, to everyone's surprise, Somasundaram stands in front of Jagadish. He says the flight is rerouted to Chennai due to some technical problems, and one hour is left for the next flight. Though Somasundaram didn't want to go to Singapore again, Jagadish compelled him so that they could repeat their plan as scheduled this time.
So Sampath is sent to buy a new doll from the shop to fix the bomb inside it. There he finds the same doll that they had already planted the bomb. Unknown to this, Sampath buys the doll and brings it. In between, the group prepared a new bomb and attached it to another doll. The team goes to the airport, meets Somasundaram, and hands him the newly made doll. While returning, a doubt had arisen that the bought doll was the one that they had made earlier. When Jagadish checks the doll and finds the address card, everyone is shocked. Sampath pulls out the card in anxiety, and the bomb explodes inside the car and kills all of them instantly. Back in the airport, Somasundaram is saved by the taxi driver, who knows all of these with the help of Mallika and Aanandan.
