Two elderly individuals fall in love with each other and decide to elope. However, their decision leads to hilarious situations that they must try to overcome.

Krishnasamy (Arjun Sarja), a respected man, and Samiyappan (Thilakan) are in a feud for several years. Amudha (Nikitha), Krishnasamy’s daughter, hates her father because she thinks that he is a killer.
A few years before, Krishnasamy was a tea master with his friend Kandhasamy (Goundamani). After his father’s death, Krishnasamy had a lot of responsibility. He fell in love with Sindhamani (Roja). In the meantime, Samiyappan, a local don, cancelled his engagement because Sindhamani’s father promised Sindhamani to his son (Raja). One day, Krishnasamy ridiculed Samiyappan in a politic function. This humiliation irks Samiyappan, so his henchmen burnt Krishnasamy’s house and Krishnasamy’s brother who was in the house died. In anger, Krishnasamy entered Samiyappan’s house and fought against his henchmen but an honest police officer (Nagesh) arrested him before he committed murder. The police officer gave him a mission: stopping Samiyappan’s illegal activities.
