The master finds Unni (Dileep) after years and brings him back to the Village.The villagers realize that Unni is abnormal and is mentally challenged. He behaves like a small boy and creates all sorts of trouble for the villagers and his parents. His main hobby is to snatch dhothi from people. He snatchs the dhothi after aiming at it with a hand gesture resembling Okay gesture. This leads to a series of comical incidents in the village.He is given Ayurveda treatment under the guidance of the church priest (Jagathy Sreekumar).

But finally Unni gets back his memory only to let out the truth that he is not Unni but Vishnu, the son of a Bangalore don (Thiagarajan).Then the story unfolds Vishnu's earlier life and tragedy. The film ends with Vishnu marrying Ammu; and Krishnankutty (Harisree Ashokan), Unni's friend and village tailor, snatching his dhothi.
