The film begins in Jaalkot village, where Thakur Ajgar Singh is the tyrant of the region. Inspector Jagdish Chandar strongly opposes his cruelty. Jagdish lives with his motherless children, Avinash and Brijesh (aka Birju).
Ajgar conspires to have him killed by two professional assassins: Lawrence and Peter. One night, the killers slay Jagdish and abduct Briju, whereas Avinash is adopted by a police commissioner.
Years roll by, and Avinash becomes a stout-hearted police official and leads a delightful life with his wife Sudha and daughter Bubbly.
Birju, on the other hand, has turned into a criminal under the tutelage of Lawrence and Peter. The duo gets him to commit crimes and live off the proceeds. They assign him a final task — to steal a jewel — soon after he is released from prison.
Meanwhile, Chanda — a victim of Ajgar — approaches Birju for help to destroy the tyrant. In turn, Birju recruits Chanda for the theft, but Chanda is apprehended.
Through Chanda, Avinash learns about Ajgar and recalls the past. He then gets himself transferred to Jaalkot.
Meanwhile, Lawrence and Peter betray Briju, but he evades them and runs away with the jewel.
Avanish encounters Birju on a train as a copassenger, and a brawl erupts. Here, Avanish recognizes Birju as his brother by his tattoo. However, he falls out of the train and is presumed dead.
Birju lands up in Jaalkot, where everyone welcomes him as Avinash. Despite being initially reckless and suborned to Ajgar, Birju breaks ranks after witnessing the tyrant's atrocities. Surprisingly, an unknown person under the veil always shields him. Meanwhile, Chanda witnesses how Birju has transformed and falls for him.
One day, Sudha reaches the village with Bubbly, setting up a potential reveal, but Briju handles the situation. Soon, he realizes that Avinash is his brother over what happened on the train.
Eventually, he reforms Ajgar's henchmen, Sunny and Mangal, turning them into approvers. However, they are slaughtered. Undeterred, Briju continues to accumulate evidence against Ajgar.
Meanwhile, Sudha learns of what happened on the train and, outraged, seeks to kill Birju, but is stopped by the man in the veil.
He is revealed to be Avinash, who apparently survived the fall from the train. The brothers then join hands in exacting revenge on those who wronged them.
