"Chat-patee" - the very word conjures up images of a sparking, vivacious personality - and that's what this lovely, lively girl (SmitaPatil) is.
But behind the sparkling and vivacious exterior hides another personality - that of a petty thief, a criminal, a pickpocket and a liar.
How could such a lively, lovely girl be such a person, and who made her what she was?
To know this, one has to go back in time a little and learn the story of two great friends - Laxman Singh (SudhirDalvi) and Ram (Dr. ShreeramLagu). Laxman Singh is a wealthy Thakur and Ram a petty Shopkeeper. Yet they never feel any difference of social status for they have grown up as dear friends together from childhood.
So much does Ram love Laxman that he accepts a jail sentence on his friend's behalf. During his stay in jail their common enemy Daulat Singh (Col. Raj Bharati) maneuvers events in such a way as to create a life-long enemy between the two bosom friends.
As a result Ram tries to take revenge on his dearest friends for a wrong which that friend was never responsible for. Ram steals the newborn daughter from Laxman's home, not realizing that the child is his own, given birth to by his wife Sita (SeemaDev) who has been given shelter by Laxman Singh.
The thirst for revenge makes Ram bring up little Chat-patee in evil ways. He makes her into a criminal, a liar, a thief and a pickpocket, little realising that she is his own daughter. During Chat-patee's merry trail of wrong doing she incidentally meets Police Inspector Pratap (Raj Kiran) who happens to be Laxman Singh's nephew. The young man takes a liking to Chat-patee and tries to reform her.
Dulat Singh thinks that Chat-patee is the daughter of Laxman Singh, and in order to grab all Laxman's wealth and property, engineers a marriage between Chat-patee and his own son Chhote Thakur (Inder Thakur).
Does Chat-patee marry Chhote Thakur (Inder Thakur)?
Does Inspector Pratap save Chat-patee from this loveless match?
Does Ram realise that Chat-patee is his own daughter?
