DSP Shiv Kumar returns home to his wife Sheetal and their young daughter and announces that he has been transferred to Bombay. Shiv Kumar has two brothers, Vijay and Ravi, who live in Mumbai. They are intelligent and capable guys, but spend their time loafing about the city and swindling unsuspecting people.

Three brothers are separated after their parents are murdered by a gangster. Years later, they find their paths intertwined around a family song.

Vijay Kumar is the illegitimate son of a construction baron, Raj Kumar Gupta and his first love, Shanti, whom Raj had given up in order to marry a wealthy heiress. Raj does not know of this son, who grows up and after his mother's death comes to Delhi to take revenge on the Gupta family by destroying the family's business and their relation with each other.

A ruthless gangster named Don is killed during a scuffle with the police. Since only DSP D'Silva knows of this incident, he recruits Vijay, who is a spitting image of Don, to replace the original Don and infiltrate his gang. D'Silva plans to nab the entire gang, but when he dies during a raid, the secret that Vijay is not Don is also buried with him.

Haunted by the past, Vijay turns to crime, while Ravi, his brother, becomes an honest police officer. Fate pits them against each other when Ravi is sent to nab Vijay.

DCP DeSilva sees a way to bring to justice the feared head of a criminal empire by recruiting a man named Vijay, who looks exactly like the crime boss. The ruse works too well, and soon Vijay finds his life in danger when DeSilva, the only one who knows his true identity, dies.
