FORENSIC is the story of mysterious serial killings in a sleepy hill station. Megha Sharma (Radhika Apte) is a sub-inspector in Mussoorie. She resides with her mother and Aanya (Harbandana Kaur). Aanya is the daughter of Megha's deceased sister Divya (Zeba Sherrif). She was married to Abhay Khanna (Rohit Bose Roy) and was the mother to Aanya as well as her twin sister, Aadya. 5 years ago, Aadya died in a freak accident in Rishikesh while the whole family had come to visit a fair. Divya couldn't handle the trauma and committed suicide. Megha blamed Abhay for these deaths. She forcibly took Aanya with her. This development added to Abhay's stress and he became depressed. Megha also broke up with Johnny Khanna (Vikrant Massey), Abhay's brother, after this incident. In the present day, a young girl, Jennifer, goes missing on her birthday from her school. Her dead body is found the next day. Megha is given the charge of handling it over her rival, Ved Prakash Mathur (Subrat Dutta), as the SHO believes that she can sensitively handle the case. The SHO also informs her that Johnny Khanna will be doing the forensic investigations. Megha is not happy with her developments but agrees with the decision, nevertheless. Johnny goes all out in collecting vital information from the crime scene, Jennifer's clothes, etc. While the investigation is underway, Aditi (Shraddha Bhatt), another girl, goes missing, that too, on her birthday. And yet again, she is found dead. Based on the foot marks found and other data, Johnny concludes that the killer is a 10 or 12-year-old child. His sketch is made thanks to an eyewitness and it's spread everywhere in Mussoorie. The town goes into a lockdown-like situation, the schools shut down and parents prohibit their kids from going out, fearing that the suspected killer-child will attack their ward. One day, Aanya goes missing and Megha finds her with the suspected killer-child, Rohan (Nikhil Chawla). Rohan is arrested and the whole Mussoorie heaves a sigh of relief. Johnny, however, has doubts about whether Rohan is the killer. Meanwhile, another girl goes missing on her birthday. This time, CCTV footage is leaked which shows that the child taking out the missing girl is none other than Aanya! What happens next forms the rest of the film.
