The plot opens with the introduction of Ravi (Prasanna), an electronics engineer who introduces himself as a youthful guy who aspires to become a businessman. He meets Viswanath (S. P. Balasubrahmanyam), the CEO of Trust Bank, in a golf course when he fights to grab a bag belonging to Viswanath from a stranger. Ravi saves Viswanath and chases the stranger. He is unable to catch the man but gets a glimpse of his face. Viswanath thanks Ravi, offers him a job in his bank, and also assures to provide a loan of Rs. 2 crores to start his own business. The bank promotes its new branch as the "world's safest bank" with the security locker designed by Ravi. Ravi works in Trust Bank for five years, but his loan approval gets rejected so many times despite Viswanath's attempts to get it approved.

Ravi meets a girl named Nandhini (Ramya Raj), a divorced news reporter, in a golf club and they become friends. Slowly, love blossoms between them. However, Ravi, once during his date with Nandhini, is attacked by Nandhini's ex-husband Raghu. He counterattacks him and goes home. At home, Ravi meets Fareed (Sibiraj), who tells that Ravi killed Raghu and that there are evidences to prove. Fareed also kidnaps Nandhini. Ravi is confident that he did not kill Raghu, but he has to obey the words of helping them rob the bank to save himself and Nandhini.

Fareed says that he is an ex-employee of Trust Bank and was fired by Viswanath for fund mismanagement. So, Fareed wants to take revenge on Viswanath by robbing Trust Bank, which will negatively impact its trustworthiness, and he wants Ravi to help him as he is the one behind the safety system design. Ravi and Fareed plan to rob the bank, which has infrared lasers and a four-leveled lock system vault. Meanwhile, Ravi records the conversations going on between them and hands it over to his assistant Devaki to save himself. Ravi demands Rs. 2 Crore, the photographic evidences of the murder from the robbers before the theft. Fareed initially gives it but takes it back and gives Ravi a bag similar to it.

Ravi discloses all the security systems to enter the vault, and Fareed and his men enter the vault. However, Ravi did not inform them about a secret exit in the vault, and he makes a plan to get Fareed and his men trapped. Ravi suddenly escapes through the secret exit, locks others inside the vault, and rushes to meet Viswanath, where he also sees Nandhini with him. Ravi gets shocked seeing Nandhini along with Viswanath and gets to know the truth. The robbery is actually a plan of Viswanath, who did it in order to grab the bag, which has evidences of his illegal affair with Nandhini, who is actually named Eswari. The stranger took pictures of Viswanath and Eswari and blackmails Viswanath for money. The stranger also safely places the evidence in Trust Bank's locker. To steal the evidence, Viswanath planned a robbery with Fareed, Eswari's brother. The man who Ravi was told to be killed by him was actually a new employee in Fareed's gang. Viswanath apologizes to Ravi for the trouble created by him and commits suicide. Fareed and Eswari are arrested, and all of Fareed's gang members die inside the vault due to lack of oxygen.

Ravi destroys all the evidence of the illegal affair of Viswanath and finds Rs. 2 Crore in the back side of his car, which actually was demanded by him from Fareed, and which he uses to start his new business.
