Simba (Ranveer Singh) lost his parents at an early age and became an orphan. Forced by life, Simba had to become a pickpocket under the guidance of the street gangster brother. In the young Simba's mind, the seemingly omnipotent gangster brother is the god of this world. In the process of stealing together, Simba and the gangster brother were caught by the police. Seeing the gangster brother nodding in front of the police, Simba's faith was broken. He finally understood that there was a more authoritative role above the gangster brother, that is, the police. In this way, Simba was determined to become a policeman, and after years of unremitting efforts, he finally sat on the chair of the police chief. However, Simba is not the kind of good man who punishes evil. He relies on his rights and status to collude with local gangster gangs, which makes the citizens dare not speak out.
