Urvasi is a rich man’s daughter up to practical pranks all the time . Mohan is a middle class orphan who shares his one room accommodation with YG Mahendren . After some teasings and bantering , both Urvasi and Mohan fall in love . Some cute duets follow. Now Urvasi is worried about her father’s approval for her chosen groon . He is a strict military man and wants his daughter to marry into a big rich family . He invites Mohan and his family to stay with him in his huge bungalow for a few weeks before giving his approval. Mohan fishes through his list of acquaintances and gets Kuyili ( a street dancer ) to become his sister, Gandhimathi ( a theatre actress) to become his mother and Radha Ravi ( an illicit liquor maker ) to be his brother . Now starts the comedy of errors . Kuyili though short in height is pretty and acts well . Gandhimati is a seasoned actress . Mohan and Urvasi are cute as a couple .Radha Ravi comes with a huge rough wig and speaks loudly because ruffians were supposed to be like that . Over all a nice family riot .
