He meets his old teacher, Kumaran master (Bahadoor) and informs him that he was running a hotel in Punjab but lost everything in the riots there. He opens a small tea-shop in the village. There, he meets his old flame Bhaagi (Sithara) who is now married. He also meets his uncle Koyikal Madhava Kurup (M S Thripunithura) who was responsible for his fleeing from the village and losing his girl. He returned to take revenge on his uncle but by the time his uncle already lost all his wealth. In the village, he also becomes friends with Anthrappayi (Jagathy Sreekumar) and Paramu (Mamukkoya). His happy second life in the village ends one night with the arrival of Chandru (Murali) from Bombay. It was revealed that Sethu was actually a henchman of Chandru in Bombay. Chandru asks him to take one more assignment or else he will reveal Sethu's real past to the villagers. Sethu had no choice but to take up the assignment and starts to Kodaikanal. In Kodaikanal he stays with Ramu (Vijayaraghavan) who was an old associate of his in Bombay. Sethu's assignment was to kill Radha (Ranjini) who teaches in a boarding school in Kodaikanal managed by Fr. Francis Arackal (Jose Prakash). One night Sethu went to murder Radha but was shocked to find her trying to commit suicide. Sethu instead saved her life and tries to found out who wants to kill her. Sethu understands that the person who wants to finish off Radha is actually Narayan Mehta (Lalu Alex) who is the boss of Chandru and Ramu. Narayan Mehta earlier married Radha as Narayanankutty for her money but later left her and made her believe that he died in an accident in Dubai. Radha met Narayanankutty, who is now a big businessman called Narayan Mehta, in Kodaikanal. Narayan Mehta orders Chandru to have Radha killed, to prevent his secrets getting revealed.
