The film starts with two flashback scenes. In 1981, a husband is waiting for his flirtatious wife to come home and take care of their son and baby daughter. The wife comes with her boyfriend and after a fight, decides to leave the husband and children. In another flashback, it's a college day festival in 1996. After a dance performance, Indu comes to enquire about her sister, Lakshmi, who is with her four friends and one of them says he would drop her home. The friends are having a good time enjoying the college day festival. In a sudden turn of events, there is a loud scream and all the students rush out to see what happened, only to find Lakshmi dead.
In the present day, out of the four friends, Rex Immanuel, Philip Idikkula, and Rashid Munna, three of them are excited to know about the return of Pappu, alias Padmanabhan, who was accused and spent time in jail for the murder of Lakshmi. Due to Pappu's stubbornness, the friends decide to get back to their studies, after a gap of 12 years. Now back from jail, Pappu wants to start everything from where they have missed it and the other three support him, taking a break from their jobs and joining the college for an M.A in Philosophy. Following certain hilarious sequences of the foursome in college, there are some interesting twists and turns to the plot, but the main aim of Pappu is to find the mystery behind the tragedy that happened 12 years ago and the killer who is among his friends.
At the end of the college festival program, he identifies that Lakshmi's killer is none other than his friend Rex. Rex reveals that he was in love with Lakshmi and on her birthday when he came to visit her, he saw Lakshmi in bed with another person which made him angry to know that two women in his life—his mother and Lakshmi—are cheaters, making him kill Lakshmi. After saying this, he targets Jenny but Pappu stops him. He becomes the convict to save Rex. The film ends with Pappu back to college and everything is back to normal.
