The story starts with floods at Ranga Saipet in Warangal District. Houses, trains, and people inundate in floodwater and Siddharth (Mahesh Babu), a young man, and his friends save the people up to their maximum effort. Eight of his friends assist him in the rescue.

On the other hand, the Chief Minister (Kota Srinivasa Rao) recommends the candidature of Pappu Yadav (Irfan Khan) for Assembly Elections. Pappu Yadav is a goonda who wishes to earn big through politics and power. To get the attention of people, he announces a sum of Rs.5 crore for flood victims.

The food that needs to reach the victims of the flood is taken elsewhere to be sold, an illegal way of earning money and backing up the flood relief fund into the pockets of the politicians. Siddharth learns of this through one of his friends and saves the stock in time. He then takes it to the flood victims for distribution.

This annoys Pappu Yadav for which Mondi Nani (Prakash Raj), Pappu's right hand, threatens Siddharth. A strife develops between Mondi Nani and Siddharth, and the latter declares that his friend Ajay (Ajay) will be contesting the next Assembly Election opposite Pappu Yadav. Siddharth and his team get accolades from the people for this decision and start campaigning. To cut the good name of the group in the people and to win sympathy, Pappu Yadav conspires for a bomb blast allegation on Siddharth and Co. Mondi Nani works for him and the mission is accomplished. Pappu Yadav declares Siddharth and Co. as terrorists and wins the election. Pappu Yadav becomes the home minister and his marriage is settled with Varalakshmi (Trisha Krishnan). Siddharth, with the help of many college students, kidnaps Varalakshmi from the marriage hall in a dramatic sequence, demanding Pappu Yadav state his crimes before a court of law.

The rest of the film shows Pappu Yadav chasing Siddharth to get Varalakshmi back. ACP Pochamma (Telangana Shakuntala) assists him and spills a little comedy with her style of dialogues.

Finally, Siddharth puts an end to the game of crooked politicians.

Remember, this film has no twists and turns.
