 All law is based on human evidence, and since human beings are what they are, their evidence cannot be infallible. Is it therefore justifiable to take the life of one man on the evidence of another? Judge Badri Prasad (Ashok Kumar) has a son, Vijay, and a daughter, Meena, who is engaged to a Public Prosecutor, Kailash Khanna (Rajendra Kumar). Being extravagant, Vijay gets into debt with Dhaniram, a vicious moneylender. Unable to tell his father, he goes to Meena and asks her to send Kailash to plead with Dhaniram, which she does. However, as Kailash arrives at the moneylender s house, he spots the Judge approaching; this being a delicate matter, he hides himself. But to his horror, he witnesses the Judge murdering Dhaniram - and to make matters worse, a petty thief who just happens to be around is arrested for the crime! Kailash, dumbfounded to see that the thief s trial takes place in Judge Prasad s court itself, decided to defend the innocent man. But now he is faced with the dilemma of trying to save the innocent thief s life; but at the same time knowing who the real murderer is, but being unable to expose him.
