Ghost

Karan Khanna was arrested because investigators found him at the scene during the murder window. CCTV footage showed him entering Barkha's apartment at 2 a.m., leaving at 4 a.m., and returning at 6 a.m., the exact timeframe when Barkha died. Combined with marital tensions and his unclear alibi, police concluded he was the prime suspect.

The film opens with the murder scene, immediately framing Karan as the primary suspect.

The CCTV footage placed Karan in Barkha's apartment multiple times during the night she died. He entered at 2 a.m., left at 4 a.m., and re-entered at 6 a.m. This timeline aligned with the estimated time of death, making him the sole suspect despite his claim that he spent part of the night at his campaign manager Bob's apartment.

The demonologist revealed that the girl who was with Karan on the night Barkha died was possessed by a supernatural force. More shocking, Karan himself was also possessed at the time, which explained his memory gaps and bizarre behavior. This possession was the true cause of Barkha's death, not a deliberate act by Karan.

Earlier scenes hint at Karan's missing memories and strange actions that didn't match his personality.

Barkha was in a secret lesbian relationship with the missing girl. She married Karan purely for fame and money, using their political image to hide her true sexual orientation. When the girl blackmailed Barkha to reveal their relationship, Barkha had her committed to a mental institute, triggering the girl's path toward revenge and suicide.

The Valentine's Day locket sent to Barkha first hints at her hidden affair.

The missing girl committed suicide at the mental institute to become a vengeful ghost. She wanted revenge on Barkha for betraying her and on Karan for being an unknowing participant in her humiliation. Her spirit targeted all three, Barkha, Karan, and later Simran, through the supernatural power of a locket she gave to Simran's father before dying.

Bob's mysterious death and warning phone call establish the ghost's deadly reach.

The locket contained the ghost's supernatural power. The missing girl gave it to Simran's father at the mental institute, asking him to deliver it to Barkha after her death. When Simran finally destroyed the locket during the exorcism, she broke the ghost's hold over Karan and ended the possession. The broken piece shown at the end suggests the curse may not be fully vanquished.

The Valentine's Day locket appears early as a key plot device connecting all characters.

Simran's father was a doctor at the mental institute where the missing girl was held. He became the link between the vengeful spirit and the Khanna family when the girl gave him the locket to deliver to Barkha after her suicide. This connection explains why the ghost eventually targeted Simran, her father's involvement made her part of the curse's web.

During the exorcism performed by Simran with help from her ex-boyfriend, the ghost seized control of Karan's body as the ritual reached its peak. At the critical moment when possession threatened to consume him completely, Simran smashed the locket, breaking the supernatural chain and freeing Karan from the ghost's influence. This act allowed him to prove his innocence.

Karan was exonerated after the exorcism revealed the supernatural truth. With the ghost's possession confirmed and Simran's evidence showing the true cause of death, the legal case transformed. The possession explained his presence at the scene and his missing memories, clearing him of criminal intent. The court could no longer convict him when supernatural forces were proven to be the actual culprit.

Bob, Karan's campaign manager who convinced Simran to take the case, went to the mental institute in Leeds to investigate the truth. He discovered critical information about the ghost's identity and called Karan to reveal the culprit. Before he could name the ghost, the spirit killed him, demonstrating the ghost's ability to reach anyone who gets close to uncovering its secrets.

Bob notices something off about Karan before his departure, foreshadowing his doom.

The ending suggests the curse is not fully over. After Karan's election victory party, a cellmate of the deceased girl sends him a box containing only a broken fragment of the locket. This ominous final image implies the ghost's revenge may continue, and some secrets, like the lingering power of the spirit, refuse to stay buried despite the apparent victory.
