Murder 3

Vikram watches a video in which his girlfriend Roshni announces she is leaving him. The revelation leaves him stunned and deeply unsettled. The emotional turmoil sets the stage for the rest of the story.

Seeking distraction, Vikram goes to a bar and encounters Nisha Sengupta. Their chemistry is immediate, and they quickly fall for each other. This budding romance becomes the new focal point after the breakup.

Nisha moves into the flat that Vikram had shared with Roshni. The couple's closeness grows as they begin to build a life together. Vikram's past with Roshni lingers in the background.

Authorities treat Vikram as a potential suspect in Roshni's sudden disappearance. The investigation yields no concrete evidence tying him to the case. The mystery tightens around Vikram while he maintains his innocence.

The house is revealed to be owned by a British woman who shows Roshni a secret, self-contained room. The room was built to hide her husband, a figure connected to the 1947 era. This discovery sets the intrigue in motion.

In a flashback, Roshni jealous of Vikram's bond with a colleague pretends she is leaving. She hides in the secret room and watches Vikram's reaction through one-way mirrors. She loses the key and becomes trapped with no way to contact him.

Back in the present, Nisha discovers the key to the secret room but does not yet know what it opens. Her curiosity will later lead to unraveling the room's true purpose. The discovery becomes a crucial turning point.

Nisha pieces together that Roshni is trapped inside the secret room. She also learns that Roshni can communicate by tapping on the pipes. This silent communication drives the effort to uncover the truth.

The investigators hand Nisha a package containing photographs that threaten Vikram's reputation. She hesitates about rescuing Vikram, fearing what might happen to him if she frees Roshni. The package pushes her to decide whether to act.

Roshni confronts Nisha, knocks her out with a glass bottle, and leaves her locked inside the secret room. The sudden act cuts off Nisha's attempt to help and shifts the power dynamic in the house. Roshni then exits the room herself.

After emerging from the secret room, Roshni discovers the package contents and the images left by the investigators. The sight shatters her further and she resolves to leave the house for good. This marks a turning point toward her departure from Vikram's life.

Roshni leaves a visible trace—placing a photo on the mirror and stitching her necklace as a sign that she is out. She also sends the room keys to the investigator who loves Nisha. The gesture both tests Vikram's fate and nudges the investigation forward.

The investigator arrives and arrests Vikram, unaware of the secret room and its key. Vikram's arrest unfolds without anyone acknowledging the hidden room's existence. This twist closes in on Vikram's fate.

In the ending, Roshni tears apart Vikram and Roshni's photograph and drives down a highway alone. She feels liberated and hopeful to leave the devastated Vikram behind. The act signals a fresh start away from the entanglements of the past.
