The college has no basic facilities, including a proper building and good doctors. Malarvizhi and her best friend Vaishali (Aparna Vinod) lodged a complaint against the college to the Medical Council of India. To save his name, PK(owner of the college) made a deal with the MCI officials to cancel the suspension in exchange for sex with a girl from the college. Vaishali, who was the girl chosen by the officials, was found raped and killed the next morning. Malarvizhi's father (Aadukalam Naren), a sincere police officer, began an investigation into PK's involvement in Vaishali's death, but he too was killed by PK. After her father's death, Malarvizhi dragged PK to court. The judge declared that Malarvizhi should not be expelled from the college and must not be harmed till the case ends. But PK indirectly troubles her through the lecturers of the college. Bairavaa, on hearing Malarvizhi's story, decides to help her fight against PK and get justice for Vaishali. He too leaves for Kallidaikurichi with her.
