Venkat Ramakrishnan (Srikanth), Sevarkodi Senthil (Jiiva) and Panchavan Parivendan (Vijay) are three engineering students who share a room in the residence of Ideal Engineering College (IEC), Chennai. Venkat is studying engineering to pursue his father's wishes over his own wish — to become a wildlife photographer. Senthil is studying to raise his family's fortunes and get them out of poverty. On the other hand, Pari studies for his simple passion in machines and devices. Pari believes that success in studying is not achieved by solely memorizing definitions given by textbooks or professors, but by understanding and applying the concepts. He believes that one should follow excellence, not success, as success will come itself if excellence is followed.
