Dayashankar Pandey

Under investigation as a suspect in her husband`s murder, a woman reveals details of their thorny marriage that seem to only further blur the truth.

Two British nationals (who were tiger experts investigating the large scale poaching of tigers in Indian National Parks) are killed by a ferocious tiger in Corbett National Park in India. This incident is followed by several other tiger attacks, and many deaths result, prompting National Geographic to send a correspondent, Krish Thapar (John Abraham) to the national park and ascertain what really happened. Thapar is accompanied by his wife Riya (Esha Deol). Bashir Khan (Parmeet Sethi) is the forest officer suspected of facilitating poaching in all National Parks that he is assigned to. A group of youngsters, consisting of Dev Malhotra (Vivek Oberoi), his girlfriend Ishika (Lara Dutta), Sajid (Kushal Punjabi) and Vishal (Vishal Malhotra), are on a hunting trip in the hopes of sighting and shooting some big prey. The youngsters' car breaks down (After Dev hits a black cat which Ishika considers very very bad luck). Bagga (Vineet Sharma), a passing by driver, gives them a lift to the farmhouse they were heading towards. Bagga convinces the group to head towards the Orbit National Park for some big game hunting. Bagga tells them that venturing into the core area of the jungle is prohibited and is very dangerous. Bagga's car accidentally hits Krish's, which also breaks down and is at the middle of the road. The two groups decide to travel together in Bagga's car, leaving a mechanic repairing Krish's car. Just a few seconds they set off, the mechanic disappears, and they believe a tiger just took him away and decide not to risk their lives to look for him. Bagga finds them a place to stay -- a guesthouse owned by Pandey (Daya Shankar Pandey). Pandey is a guide who agrees to lead them the next day to the core area, where tigers live, for hunting. Pandey disappears the very night and his body is found in the wild the next day by Bashir Khan, with his head chopped off. Krish starts to be suspicious about the real cause of the recent rising deaths in the jungle, as he is an animal expert and recognizes Pandey is not killed by a tiger or any animal. Warned by Bashir Khan and scared, the group decide to leave the jungle. Before they depart, they find Sajid missing, again not by an animal. Dev, close friend to Sajid, assumes the latter is going to the core area alone for hunting. However, the group decide to leave without Sajid. Expectedly, Sajid joins the series of mystery deaths and is found with his head chopped off. The rest are soon confronted by three tigers on the way. Kaali Pratap Singh (Ajay Devgan), who claims to live in the jungle, saves them from the upcoming tiger attack. On their continued way out of the jungle, they find the road is blocked by rocks due to the landslide caused by rain. Kaali shows up again and agrees to lead them out of the jungle. On the way the car has a minor accident when Bagga cant take his foot off the gas pedal. The group is forced to take a break while Bagga repairs the vehicle. Kaali appears to be very knowledgeable about the jungle. Krish, who is now more curious about the mysterious deaths, asks him if he knows what's behind those deaths. Kaali answers that there was a mad guide in this jungle, who always led tourists to wrong places to make them killed by animals (he did this as he didn't like the exploitation of animals and forests by humans and wanted humans to learn a lesson). Angry villagers later found about it and beat him to death. But his spirit -- the ghost -- remains in the jungle and keeps killing tourists. But none of them believe Kaali's story. Bagga later disappears when repairing his car, rising the fear among the rest. Vishal is also killed by their car explosion a few moments later (the group tries to cross a small wooden bridge to get to the other side, but the car gets stuck and leaks gasoline. Vishal acts weird and refuses to get out of the car and is blown away when a stray cigarette that he threw in the water, ignites the fuel). The rest carry on and reach a deserted guesthouse in the evening, outside which there is a well. All go to sleep after being warned by Kaali not to get close to the well. Riya wakes up thirsty in the night. She decides to get water from the well despite Kaali's warning, and is later accidentally hung by her foot in the well and dies. The rest figure out Riya's death and try to pull out her body, while Dev suddenly realizes that Kaali does not have a reflection in well's water. He also sees that Kaali is not visible in any of the videos that had been recorded by Vishal so far. He realizes that the story Kaali told them is true and he is the ghost referred in the story. Dev makes an excuse to push Kaali off and convinces the others that Kaali is a ghost. They decide to escape from Kaali. They encounter several accidents on their way out of the jungle, apparently arranged by Kaali, but finally manage to escape. Krish now knows what's behind those mysterious deaths but he is not going to tell anyone because no one is going to believe him. Meanwhile in the jungle, Kaali keeps killing tourists.
