One day, Shivani finds out that Pyaari has been missing from her shelter home from 5 days and begins an investigation, where she finds out that the mastermind behind this kidnapping is a Delhi-based kingpin named Karan Rastogi (Tahir Raj Bhasin), who runs a cartel involving child trafficking and drugs. Shivani takes the task personally, going beyond her job and duties to nab Karan, Shivani forces Rahman to reveal the names of Karan's associates and comes across Sunny Katyal (Anant Vidhaat Sharma), a car-dealer who operates Karan's trafficking business in Mumbai.

Determined to catch him, Shivani tracks down Karan's aide, Wakeel. Karan, angered, makes sure that Pyaari is sold and raped every day. As a warning, he spreads fake news that Shivani's husband has misused his profession as a doctor to molest a female patient, causing Bikram to be thrown off-duty.

Meanwhile, Karan's right-hand man Mattu (Aman Uppal) gets a contract to host a party full of prostitutes from a man named Tandon on the behalf of a minister in Delhi, Taneja ji.
