Murder

Vikram, a renowned fashion and wildlife photographer, watches a video in which Roshni announces she is leaving him. The revelation shatters his sense of reality and triggers a downward spiral of heartbreak and confusion. He drinks to dull the pain as the relationship appears to end.

At a bar, Vikram meets Nisha Sengupta and the chemistry between them quickly ignites. They share a connection and begin a new romance, providing Vikram with a respite from his broken relationship. The encounter marks a fresh chapter in the story as Roshni's departure looms.

Nisha moves into the flat that Vikram shared with Roshni, bringing a sense of stability and the promise of a new start. Vikram starts to open his heart to Nisha again, feeling hope for the first time in a while. The dynamic shift also stirs whispers about the past between Vikram and Roshni.

Vikram becomes a suspect in Roshni's disappearance, and investigators pull his name into the case. The police find no hard evidence tying him to the missing woman, but the doubt hangs over him. The situation intensifies as the case stalls and public suspicion grows.

The house is revealed to be owned by a British lady who shows Roshni a secret room built to hide her husband, a former Indian Army soldier from 1947. The room is self-contained, with one-way mirrors that let observers watch without being seen. The reveal ties the present mystery to a half-forgotten past.

In a flashback, Roshni pretends she is leaving Vikram out of jealousy and traps him into reacting on camera. She hides in the secret room, watching his responses through the mirrors. She loses the room’s key, leaving herself trapped with no way to contact the outside world.

Nisha discovers the key to the secret room but does not know what it opens. She pockets the object, sensing it is important but unsure of its purpose. The mystery deepens as the key sits unused for now.

Roshni begins tapping on the pipes, trying to communicate with Nisha from inside the room. Nisha realizes Roshni is alive and trapped, and she grows determined to understand the room’s purpose. The two women are connected by the secret but separated by walls and time.

As investigators deliver a package containing images of Vikram with a colleague, Nisha is torn between helping Roshni and protecting her own romance. She hesitates, weighing the risk of losing Vikram against saving Roshni. The package becomes a catalyst for a crucial decision about whether to intervene.

Nisha approaches the door to rescue Roshni, but the moment is chaotic: Roshni knocks Nisha out with a glass bottle and locks her inside the secret room. She then exits the room and leaves the area, effectively escaping the immediate danger. The room’s secrets remain hidden from both Vikram and the investigators for the moment.

Roshni sees the package and the images, which shatter her trust in Vikram and his colleague. She decides to leave the house for good, placing a photo on the mirror and sticking her necklace as a sign that she is out. She also sends the room keys to the investigator who loves Nisha.

With the evidence unseen by Vikram and the investigators, the investigator arrives and arrests Vikram, believing him culpable in Roshni’s disappearance. Nisha remains locked in the secret room and unaware of the arrest, trapped by the house's hidden design. The true mystery of the room remains concealed from those outside.

On the highway, Roshni tears their photograph and drives away alone, relieved to be free from the ruined relationship. The ending sees her moving toward an uncertain but hopeful future, while Vikram faces the consequences of the arrest. Her departure marks a new, independent chapter for her.
