[1] Running away from her fantastically wealthy but selfish father, king Vijayaragunath Boobapathy and Asha Devi, his new partner especially, Vijayanirmala Devi, princess and unique heiress, hides her real identity by claiming to be Uma, a distant cousin, with Balumurali, at a meeting, when she is welcomed within her humble but happy family led by the mother of the latter, soft and sweet Abhirami, also consisting of her older brother Murugesan a bus conductor, of both sisters of the young man (Balu), Kanchana, the girl, Sulochana, the biggest and Ramu.

While all this small world is waltzing in a dream, one night, Abhirami believes to have poisoned her children when she notices that a lizard is drowned in the bowl of milk which she has just given them.

The unexpected arrival of Kadheresan, the father of the "real" Uma, lays bare the truth of Vijayanirmala, casting a chill on Balu, feeling deceived since the beginning.

Their reunions are shortened because Abhirami, sick person at heart since the death of her husband, is at the moment in a critical state and could die if she is not immediately operated on.

Sulochana emits the idea to denounce Vijayanirmala, who is immediately reprimanded by Balu and so by Abhirami, who prefers to die than to send back his son's lover.

In the greatest secrecy, Vijayanirmala makes a decision: to surrender to her father in exchange for the operation of Abhirami, to take all the hospitable expenses under his responsibility.

The monarch, in the view of this distressing show, cannot refrain from ordering to the pilot to land, in the happy bewilderment of his daughter, Vijayanirmala.
