The predator keeps on challenging Shivani with his every crime.Shiv "Sunny" Prasad Yadav (Vishal Jethwa) is a juvenile, who likes to abduct and sexually assault "Nackhchari girls". His latest victim was in Kota, Rajasthan and Brij Shekhawat (Sumit Nijhawan) is the investigating officer when Shivani arrives to take charge. Shivani quickly establishes the brutality the rapist displayed while raping and then killing Latika (Tejasvi Singh Ahlawat). Politician Panditji (Prasanna Ketkar) hires Shiv (who is a hit-man from Meerut) to kill a journalist who is creating trouble for him. Shiv watches Shivani vow in a press conference promising the catch the Latika rapist and murderer.Shiv also has a deep-rooted anger against women who challenge men's authority. He decides to teach Shivani a lesson. He breaks into Shivani's home and steals her Saree. He then uses the same Saree to strangle and hang the Journalist Kamal Parihar (Anurag Sharma). Shivani gets the message that the sexual predator is directly challenging her. But Shiv has used a tea stall owner directly opposite Shivani's office & killed him along with Kamal's wife to show that they were having an affair. Then he takes the tea stall owner's place and uses that to gain entry into Shivani's office.Once there he finds that Shivani found an eyewitness (a boy of a day laborer) to the car that Shiv used to kill the Tea stall owner and Kamal's wife. Shivani brings the boy into her office to make a sketch. Shiv very smartly uses drugs (mixed inside the boy's milk) to bring the boy into the loo and then murder him. He places the body on railway track which is chopped to pieces. The news leaks that a boy in police protection committed suicide. Shivani is transferred and has 48 hours. She vows to capture the rapist. She approaches the case from another angle and traces who ordered Kamal's death. through Viplaw Beniwal (Sunny Hinduja) she reaches Panditji and finds the location where their assassin was hidden. Once there she finds Shiv's latest sexual assault victim, who is still alive.Shiv gets advance warning from Panditji and vacates before Shivani arrives, but then injures himself and throws himself in front of Shivani's car. Shivani recognizes him as the tea stall owner and takes him in her car. Once in, Shiv attacks Shivani, who was anticipating this attack. Shiv manages to escape after injuring Shivani. Shivani then issues a social media video showing Shiv's face and asking the people of Kota to arrest the guy if they see him. Shiv responds by kidnapping Panditji's granddaughter and asking to pressurize Shivani to issue an apology to Shiv on social media. Shivani tracks Shiv via CCTVs all over Kota and manages to rescue the girl before Shiv can do any harm to her.Now Shiv reaches out directly to Panditji's boss Viplaw Beniwal and offers to kill his opposition Suananda (Richa Meena) in exchange for his own safety and safe passage out of Kota. Shiv challenges Shivani to stop him from sexually assaulting another woman. Brij suggests Shivani that Viplaw has perhaps hired Shiv to murder Suananda as his party has decided to give a ticket to Sunanda in the upcoming elections and Viplaw wants to stop that at any cost. Shiv abducts Sunanda and hides them near the location where she was abducted, while sending Shivani on a wild goose chase. Shivani refuses to take the bait and uses her wits to track Shiv down.Shiv had occupied a house near the temple where Sunanda was abducted and also taken hostage the daughter of that house and locked them inside a room on the first floor. The parents try to keep Shivani out, but eventually figure out that she is their best chance to save their own daughter. Shivani tries to rescue the ladies but is captured by Shiv. She rallies the ladies to turn the tables on Shiv and drags him out of the house, on the streets and beats him senseless. The whole Mohalla joins her.
