Moorthy Moorthy is excited to meet his close friend Satya and their other college friends at a reunion after five years, apparently planned after Satya's letter. Unfortunately, Satya's father arrives to inform them that he is in a coma. A psycho-test conducted by the Doctor reveals fragments of Satya's early years in college. He had fallen in love with Jothi after she helped him board a train he was about to miss. When Jothi joins the same college where he studied, he is overjoyed at the chance to see her more often, but he never confesses his feelings, a silence that lasts until the farewell day when he overhears Jothi advising a friend about love. Satya's narration ends here, as he begins shouting in the doctor's room.
Following the doctor's advice, Moorthy, Chandru, David, and a few others decide to pursue a 30-day recreational treatment to wake him from the coma. They contact almost all the students, their retired Principal, and lecturers from batch 2000 to help with this effort. They find Jothi to be engaged, but Moorthy hides the truth that Satya loves Jothi to make her agree to their plan, and she agrees. The group of students then transforms their present college (2005) into an old college, as it was in the year 2000, so Satya can relive those days. Satya is brought to the college and slowly begins to believe it is the same time when he studied. He gets reminded of his love for Jothi and begins to wait for the farewell day, just as he was waiting five years ago. Even Jothi realises that Satya had loved her in the past, and the entire plan is to make Satya propose to her on the farewell day. So, she angrily quits the plan and leaves for her home. On the night before the farewell day, he realises that the current situation he is facing is in the year 2005, not 2000, as he was thinking. Slowly, he begins to remember what exactly happened five years ago on the farewell day. Satya is seen waiting for Jothi outside a temple to confess his love when a corrupt police officer, with whom he had a previous altercation, attacks him. He suddenly wakes up and comes back to the present day, realising that his friends have recreated their entire college days after 5 years. On the farewell day, Jothi returns to college, and his friends urge him to propose. Satya goes to Jothi and asks her to stop acting that his friends had asked for and not to fool herself. He thanks her for saving him a second time and walks away without expressing his love. Jothi comes running towards Satya and tells him that she needs him and regrets wasting the five years not knowing his love for her. The couple then hugs each other, followed by cheers from all the college students.
