Madhavan (Dileep) is a clever thief who robs for a living and is well known in the village. He is following the principles of his mentor Mullani Pappan (Mala Aravindan) who trained him to be a thief when Madhavan was a young boy. Meesa Madhavan got his name by the popular saying that if Madhavan rolls his Moustache (Meesa in Malayalam) looking at someone, he will rob his house that night.
