_Do Thug_ is the story of two con-artists, *Ravi (Shatrughan Sinha)* and *Bijli (Hema Malini)*. They begin with petty crimes like pickpocketing and eventually start working for a notorious smuggler and criminal *Ranjit (Ajit)*, carrying out smuggling operations for him.
Ranjit murders a wealthy businessman *Madan Seth (Shatrughan Sinha in a double role)*. He frames *Ravi* for the murder and blackmails him into continuing to work for his criminal activities. Ranjit threatens to hand Ravi over to the police if he refuses to cooperate.
Meanwhile, *Bijli's* father *Brigadier Ram (Nisar Ahmad Ansari)* is also mysteriously murdered. During the investigation, it is revealed that Ranjit is also the killer of Bijli's father. Bijli seeks revenge for her father's death.
Ravi and Bijli gradually realize that Ranjit has destroyed both of their lives. Ravi discovers that Madan Seth, for whose murder he is blamed, was actually his lookalike. Police Inspector *Dheeraj (Dheeraj Kumar)* is also pursuing Ranjit's gang.
In the climax, Ravi and Bijli join forces to gather evidence against Ranjit. After a major confrontation, Ranjit is exposed. Ravi proves his innocence in court regarding the murder charge, and Ranjit is sentenced. At the end of the film, Ravi and Bijli decide to leave the world of crime and start a new life.
*Shatrughan Sinha plays a double role in the film*: 1. *Ravi*, a con-artist 2. *Madan Seth*, a businessman who is murdered.
