Printed Indian currency from the Reserve Bank of India security press at Nasik with an estimated value of ₹ 1000 crores, is stolen from a train by T. T. Vikram, a gangster and drug dealer living in London. The container is shipped off by Vikram's henchman and is on the move. The access card of the container goes to the possession of pop star Chandralekha, an acquaintance of Vikram. CBI SP Lakshminarayanan is assigned to track down the stolen currency within the next ten days, on time for the upcoming budget allotment for the fiscal year.

Lakshminarayanan tracks down Chandralekha who tactfully escapes from him and tries to reach Vikram, when she comes across two small time burglars – Kadhir and Azhagu. The duo are on the run from the police after a successful burglary in the countryside. A village belle Rasathi, who tries to escape from her abusive relatives also tags along with the thieving duo. Chandralekha and the trio end up traveling together due to circumstances. When Chandralekha tries to double cross the thieves and escape, they steal her purse containing the access card as revenge. Realizing this, she comes back to them and only then does the duo realize the actual worth of the access card. They all make a plan to pursue the money container somehow, but Vikram tries to chase down and kill all of them to get the card back at any cost.

While on the run from the police and Vikram, they come across the very same truck containing the loot and manage to bring it under their possession. They hide it away from prying eyes with the entirety of the loot still intact inside the container. With Lakshminarayanan and his brigade of CBI officers close at his tail, Vikram stops at nothing to get his loot back, but is outwitted repeatedly by the thieves. Vikram finally manages to find Chandralekha, gets the access card from her and she is left to die in the forest, but is rescued and taken into custody by Lakshminarayanan, who interrogates her and she cooperates with them to find the container.

Meanwhile, Kadhir and Rasathi are mutually attracted to each other but Kadhir sacrifices his love for her after realizing that his best friend Azhagu is also in love with Rasathi. Rasathi, who does not want to continue with this love triangle, opts out and leaves them both, but Vikram captures her. Kadhir and Azhagu, in a bid to save her, point to the location of the currency container and Vikram escapes with the loot on a train, taking Rasathi as a hostage.

Lakshminarayanan finds that the loot is being transported on a train and is in hot pursuit, while Kadhir and Azhagu also get on the train to save Rasathi from Vikram. They save Rasathi together and subdue Vikram, who falls off the train. Azhagu also steals the access card from him. Now that they are finally in possession of the loot, Kadhir and Azhagu playfully argue about who would marry Rasathi and leave the other to manage the loot, each indicating that they are more interested in the money than their love for Rasathi, so she grabs the access card and throws it away and chases them around.

Lakshminarayanan arrives at the nick of time and takes the access card and the currency container back to the Indian government where it actually belongs and finally restores order.
