All the victims were unmarried and pregnant and were then aborted and dismembered. Joy, a gynaecologist, is arrested and the town's people lose respect for him.

Joy's bail application is rejected by the court for all found evidence is against Joy. Rastogi suggests that Sona prove Joy's innocence by killing one more girl in the same way the previous six were killed to prove that the killer is not Joy.

She chooses her neighbor Anushka Tiwari, an unmarried pregnant girl. News of Anushka's death reaches police, making the court believe Joy is not the killer. He is granted bail.

Joy is also saved by the doctor and alive, but escapes from the hospital before anyone is aware. Rastogi, who is now revealed to have known Joy's crime already, and possibly had a role in those killings, meets Joy and gives him shelter.
Shubhra Gupta in her zero-star review for The Indian Express stated "Nothing, not Fernandez in her perfectly coiffed curls, nor Raina trying very hard to appear as if he knows what’s going on, nor the sundry others who come and go, help. Nor, I’m forced to regretfully report, Bajpayee, who should have known better."[7] Rohan Naahar of Hindustan Times said "Not only does it disrespect your intelligence, it pretends --for a brief time towards the end -- that it has been in on the joke all along. It has none of the tongue-in-cheek chuckles that producer Farah Khan’s Main Hoon Na did, but is, instead, a strong contender for one of the worst films of 2020."[8]
Jonathon Wilson of Ready steady Cut gave the film 3 out of 5 saying "A genuinely compelling premise makes Mrs. Serial Killer (Netflix) a much better showcase for Jacqueline Fernandez than the woeful Drive."[9]
