The only son of Sardar Sangram Singh (Sohrab Modi), Mangal, is provoked into a fight with two men, which he accepts and wins, killing the two challengers. The families of the deceased young men approach Shahenshah Jehangir (Chandramohan) for justice, and Sangram Singh, trusting the justice of his employer, entrusts his son to the justice of his majesty. Jehangir makes it clear that his law is clear and there are no exceptions, and he orders the execution of Mangal, ignoring the pleas of Sangram Singh. Then a woman (Sardar Akhtar), who husband has been killed, rings the bell for justice. Jehangir appears to hear this matter, and he is told that this woman's husband has been killed by an arrow, but the woman is hesitant to name the killer for fear of repurcussion. Jehangir, however, assures her that there will no repercussions, and she names the killer as his queen, Noor Jahan (Naseem Banu). This throws Jehangir into a quandry, as now he will have to apply the same law as he has been governing others with namely: "A life for a life".
