Raju (Raj Kapoor) is a poor, friendly orphan who wins his bread by singing songs. One day, he sees an injured man and helps him. Later, he is kidnapped by a few bandits who mistake him to be an undercover policeman. It then turns out that the injured man he helped is the leader (Sardar) of this gang. The Sardar takes good care of Raju and treats him with honour. Sardar’s daughter Kammo (Padmini) falls in love with Raju. Kammo and Sardar convince Raju that they are good bandits who are making sure that wealth is equally distributed amongst people.
On one of the lootings, Raju witnesses the murder of a newlywed couple. He decides to go to the police and leaves the gang. One of the bandits, Raka (Pran), kills the Sardar and takes over; he wishes to forcibly wed Kammo. When Raju tells all the truth to the police, they decide to confront and kill the bandits. Raj begs the police to not kill them but is shunned. Raju is then posed in a dilemma of what to do and finds himself helpless when he sees police stooping just as low to stop crime.
