The story is based on Rajasthan's Kachcha Baniyan (Chadhdhi Baniyan) gang. This gang refers to some well organize gang at certain parts of North India which includes Rajasthan, Punjab and Haryana, Uttarakhand, MP, etc. Most criminals of these gangs are originated from Rajasthan. The attackers are known as Chaddhi Baniyan Gand because they wear only undergarments. For their safety, they put black lubricant, oil, or mud on their bodies so no one can capture them due to moisturizer.
