Mrs. Serial Killer

Sona tells Joy that she is pregnant, marking a new personal milestone for the couple. This revelation contrasts with the dark rumors looming over Joy. The moment sets the stage for the conflict between love and suspicion that follows.

Inspector Imran Shahid arrives at Sona's house under the pretext of collecting evidence against Joy. Sona suspects that Imran intends to frame Joy and resents his presence. Tensions rise as the investigation sharpens the divide between them.

News of the serial killings shocks the town: six unmarried, pregnant girls vanish and are later found dead. The bodies are discovered in an isolated house owned by Joy, and he is arrested. The community loses respect for him as the case intensifies.

Sona visits Joy in prison to reaffirm his innocence and to seek help. He urges her to contact Rastogi, a famed lawyer he had previously saved. The exchange deepens Sona's belief that a legitimate defense can still prove Joy's innocence.

Joy's bail application is rejected as the case mounts against him. The authorities show little room for doubt given the collected evidence. Sona clings to the hope that Rastogi can mount a compelling defense.

Rastogi suggests a drastic tactic: prove Joy's innocence by killing one more girl in the same way as the previous victims. Sona reluctantly agrees, driven by fear and the belief that there are no other options. The idea marks a grim descent for Sona's ethics.

Sona identifies Anushka Tiwari, a neighbor who is unmarried and pregnant, as the target. She plans to abduct Anushka to stage her death and implicate it as Joy's crime. The plan proceeds in secrecy, setting dangerous events in motion.

News of Anushka's apparent death reaches the police, and the court believes Joy is not the killer, leading to his bail. The public narrative shifts, allowing Joy to walk free for the moment. Sona's fear intensifies as the trap seems to work.

After Joy returns home, Sona shows him Anushka, who is still being held captive. Joy reveals that he did not kill Anushka; he found an unclaimed body and dressed it to resemble Anushka's. The revelation confirms to Sona that Joy was indeed the killer they’re looking for.

Anushka's boyfriend Sid tracks the case and discovers Anushka alive in the basement of Joy's clinic. He tries to free her but ends up locking himself in a cupboard. The discovery escalates the danger and raises the stakes for everyone.

Sona wakes up in the night and finds Joy missing; she drives to the clinic to confront him about Anushka. She realizes that Joy is the actual killer and is about to kill Anushka again. The night turns into a deadly confrontation.

Joy explains the motive behind his monstrous acts, revealing his hatred for unwed pregnancies and his traumatic past. He pins Sona down with a scalpel while Sid and Imran struggle to intervene. Imran manages to contact help and tries to coordinate a rescue as Anushka's life hangs in the balance.

Imran arrives but is immediately restrained by Joy. He eventually frees himself and helps Sona, Sid, and Anushka escape from the clinic. The group fights through the peril to reach safety.

In the climactic struggle, Joy stabs Sona as she throws herself in front of Anushka and Sid. Imran then stabs Joy from behind, seemingly killing him, though the film hints at Joy coming back to life. The chaotic moment ends the immediate threat for the survivors.

Sona wakes up in hospital with the loss of her baby and the emotional weight of events. Anushka survives and declines to file a case against Sona. Rastogi is revealed to have known about Joy's crimes and offers him shelter, leaving the ending with ambiguous loyalties.
