Rajni comes from a village to chennai only to realize he is a son of multi millionaire. His dad's will states that "If Rajni does not turn up for a long time, the wealth should be donated to a charity. If Rajni turns up he should spend a huge amount (30 crores INR) in 30 days. The money should not be gifted or converted into any other form of property". The charity is in the hands of wrong people. So though Rajni is not greedy for money he accepts the challenge of spending 30 crore INR in 30 days. The rest of the story is about how Rajni manages to succeed in thwarting the attempts of villains (charity owners) and accomplishes the task.
