One day, Padbanabhan called Philip, Rashid and Rex.He tells that he was released after 12 years of imprisonment. He told them about a new suggestion like joining back at the same college as seniors for the PG course. Even though they were hesitant first they eventually agreed to rejoin the college for PG at Ernakulum Maharaja's college, M.A Philosophy.
The movie forwards with the incidents that happens after they rejoin the college. But there is a purpose for them to why they joined back at the college.
