He is the son of flower sellers (Rajesh and Yuvasri), with Thapaal Thangavelu (Vadivelu), who provides as much laughter as the posts he delivers. Life is a long, sunny adventure for Murugesan, who beats people up, sells his grandfather’s land, runs over rooftops, and incurs so much of his father’s wrath that he is prophesied to meet a horrible end. Not that this gloomy prospect affects him – he continues on his own sweet way until he runs into Parijatham (Poonam Bajwa), a demure, fair-complexioned, striking Iyer girl, the daughter of Panjami Iyer (Y. G. Mahendran) and the younger sister of Gayathri (Simran).

Several twists in the tale occur in a quick fashion, and Murugesan and Parijatham are bound in a net from which, seemingly, there is no escape.
