Three friends Thamizh (Gokulnath), Cherry (Meghna) and Singaram (Bala Saravanan) are meeting at their reunion. They are being drawn into a bet to prove the presence of ghosts by a rich schoolmate Prosper (Bobby Simha). This leads them to a journey to five different places around the world suspected to be haunted. Namely, events which had unfolded in Japan, Dubai, the mid-sea of the Bay of Bengal, a highway in Andhra Pradesh, and a remote ATM booth in Tamil Nadu.

That night, Cherry gets a call from her lover Salim (Ajai), and with shock and fear, she utters one word: "accident". The three friends visit the place and find Salim dying. Before dying, he narrates the incident and records it in his camera.

As they watch the movie, the same incidents start happening to them as shown in the movie. Soon after, all of them are killed, and Ajay was able to bury the CD. The CD was found, but before they could get hold of it, all three friends are killed by the ghost. Prosper, after winning the bet, reclaims and rejoices his prize, a Yamaha RX 100. After hearing the doorbell ring, Prosper opens the door, on
