Murder Mubarak

Tambola Night marks the film's opening and introduces the Royal Delhi Club's members and staff. The festive atmosphere hides underlying tensions and rivalries among the upper-class regulars. This setup lays out the social dynamics that propel the mystery forward.

Early morning after Tambola Night, the club gym becomes the scene of tragedy as Leo Matthews dies when a heavy barbell falls on his windpipe. ACP Bhavani Singh is assigned to the case with SI Padam Kumar. The club president Bhatti treats it as open and shut, but Bhavani suspects murder because CCTV is obstructed by balloons and the club cat Hariya appears sick.

Roshni Batra, Cookie Katoch, and Bambi Todi, who saw the body, point to Aakash Dogra as Leo's lawyer during a club fight. Bhavani notes signs of a staged crime such as balloon coverage of CCTV and the sick cat, suggesting a planned murder. The investigation deepens as motives and relationships within the club come under scrutiny.

Aakash admits he helped Leo during a drug case, tying the murder to illegal activity within the club. The women allege Shehnaz Noorani had an affair with Leo, while Rannvijay Singh is said to have an affair with Ganga. Rannvijay becomes defensive about Ganga, boosting Bhavani's suspicions.

Leo's autopsy reveals an absurdly high presence of the drug Pinko Haathini, a substance that would incapacitate a person. Bambi overhears this forensic detail and realizes the murder may involve drug tampering. The clue intensifies the mystery surrounding Leo's death.

Bambi explains that Leo threatened to expose her kleptomania, and they trace donors at Shepherd s Orphanage where club donations are listed. The orphanage donor list names several club members, renewing interest and suspicion. This link between charity records and the club members deepens the case.

Aakash and Bambi learn that Yash Batra is involved with drugs and that Ajay Kumar is Ganga's husband in drug dealing circles. They break into Yash's home and uncover packets of Pinko hidden in his place. The discovery ties back to the club's inner circle and the drug supply chain.

At Leo's funeral, Guppie Ram does not attend. When questioned, he recalls Leo had many sins, hinting at a guilty conscience but failing to provide clear answers. His dementia prevents him from speaking coherently about the case.

On the club election day, Cookie presents sculptures of Shehnaaz and Rannvijay as tokens. Guppie Ram's cat Hariya goes missing and is found burnt in the kitchen oven, driving him to suicide with a flare gun. The events create a wave of guilt and distraction in the investigation.

A kitchen garden excavation reveals a human skeleton. Forensics initially suggest Ajay Kumar, but Bhavani Singh suspects a deeper link. The skeleton's discovery precipitates Rannvijay Singh's arrest as suspicion widens beyond the obvious suspects.

Blue crystals in the skeleton s eye socket point to Cookie Katoch s sculptor connection. The detectives locate two busts of Mother Teresa she gifted; one remains at Rannvijay's house while the other is missing from Dogra's home. Aakash is also found returning to the first anniversary party, and footage of key events resurfaces.

Ajay Kumar is captured alive and confesses that Aakash wanted him jailed. Bhavani then reveals that the skeleton is actually Anshul, Bambi's dead husband, not Ajay. Aakash is defiant but ultimately accepts a prison sentence, while Bambi s lover Yash remains implicated.

Bambi confesses that Anshul was having an affair with Ganga and wanted a divorce. Anshul allegedly raping Ganga is cited as a motive; Guppie Ram helped hide the body by pouring acid on the kitchen garden. Leo s blackmailing and Hariya s fate contribute to the motive, and Bambi ends up incarcerated while Aakash remains free as her lawyer.

In the epilogue, Bhavani advises Aakash to stay out of Bambi s case. It is revealed that Aakash has no girlfriend in Kolkata, suggesting a detached personal future after the case. The ending hints at unresolved social dynamics beyond the courtroom.
