Aaj Ka Mahatma (1976)

Randhir and Ranvir Verma are twins. Randhir is straightforward, while Ranvir is a petty criminal. These petty thefts add up, and soon the police arrest Ranvir, and he is sentenced to prison. In prison, Ranvir incurs the wrath of a gangster, Tony, and is killed. Randhir undertakes to find the killer, and gets himself arrested, and imprisoned to get to see who the killer is. After getting out from prison, Randhir plans to avenge his brother's death, without knowing that he himself could endanger his very life, as well the life of his girlfriend, Mala. The song "Chandni chand se hoti hai, sitaron se nahin, pyar bhi ek se hota hai hazaron se nahin..." is still popular.
