Three friends—Thamizh, Cherry, and Singaram—reunite and reminisce about old times. Prosper challenges them to prove the existence of ghosts and offers a massive prize if they succeed. The dare pulls the trio into a high-stakes hunt across haunted locations.

To prove the supernatural, they agree to search five reputedly haunted places. Prosper outlines the itinerary: Japan, Dubai, the mid-sea Bay of Bengal, a highway in Andhra Pradesh, and a remote ATM booth in Tamil Nadu. The stakes are high, and the trio feels compelled to take the risk.

The trio travels to Japan and attempts to capture a ghost on camera. Despite their best efforts, the haunting remains elusive and no clear footage is obtained. The first hunt ends with disappointment and mounting tension.

In Dubai they again witness eerie phenomena but fail to document a definitive ghost. The absence of proof intensifies doubt and pressure on the team. The prize’s lure weighs on their every move.

Sailing the mid-sea Bay of Bengal, the group experiences unsettling events aboard the boat but cannot film conclusive evidence. The fear grows as the mission drags on without proof. The hunt becomes more perilous than the ghosts themselves.

On a lonely highway in Andhra Pradesh, strange occurrences surface again, yet nothing they can film clearly is captured. The strain of the mission tests their friendship and resolve. They wonder whether the ghosts are manipulating their every move.

At a remote ATM booth in Tamil Nadu, a haunting is felt and an apparition appears, but definitive footage remains elusive. Doubt and fear begin to erode their confidence as the clock ticks on the prize. The journey backfires as proof once again evades them.

A pen drive holds footage of a ghost killing an ATM guard and falls into the hands of others. Bosskey, who owns the security company, learns of the enormous reward and demands 50 lakhs for the pen drive. The pursuit of money and paranormal proof becomes ethically murky.

Cherry seeks 50 lakhs from Prosper, but he attempts to take advantage of her in a sleazy manner. She is furious and returns home to recount the incident to Thamizh and Singaram. Trust among the friends falters as fear and greed collide.

That night, Cherry receives a chilling call from her lover Salim, who whispers the word 'accident.' The warning spurs the trio to investigate the threats looming over them. They prepare to confront the danger that follows them.

Salim and his companions are travelling by car when they find a CD claiming to be an unreleased movie. As they watch, they begin to experience the same haunting events from the film. Before dying, Salim tries to document the truth and to bury the CD.

The ghost relentlessly escalates and eliminates the three friends one after another, validating the film's deadly linkage to the CD. The scenes from the unreleased movie seem to mirror their fates as the haunting closes in. Salim dies, having buried the CD to prevent its spread.

Prosper reclaims the prize after the trio’s deaths, believing the challenge is over. He celebrates with a Yamaha RX 100 as the symbol of his supposed victory. The triumph is hollow, tainted by the grim events that preceded it.

A ghost tracks Prosper to his home and, when he opens the door, kills him. The haunting asserts its power and serves as a fatal warning about seeking proof of the supernatural. The story closes on a chilling note of vengeance.
