Thangamani (S. Ve. Shekher) and Rangamani (Murali) are close friends. Rangamani, an unemployed youth, is in love with Meena, the daughter of a rich man (Bailvaan Ranganathan). Thangamani is the son of a leading lawyer (Venniradai Moorthy), who is also the legal advisor to Sivagangai Gopalakrishnan (S. S. Chandran), who is a successful businessman.

Rangamani wants to marry Meena and settle down in life. Rangamani lies to Meena's father that he is the son of Sivagangai Gopalakrishnan and gets engaged to her. Thangamani comes across Lakshmi (Pallavi) and falls in love with her. He misunderstands Lakshmi to be Sivagangai Gopalakrishnan's daughter. Much confusion follows and the film follows Rangamani and Thangamani's love story.
