The film stars Ajay Devgn, John Abraham, Vivek Oberoi, Esha Deol, and Lara Dutta.

The story focuses on a wildlife expert, his wife, and a group of friends who battle against a mysterious entity in the fictional Orbit National Park (alluding to the world-famous Jim Corbett National Park, Nainital, Uttarakhand) for their lives while being helped by a mysterious tour guide.

A group of youngsters, consisting of Dev Malhotra, his girlfriend Ishika, his friends Sajid and Vishal, are on a hunting trip in the hopes of sighting and shooting some big prey.

Kaali responds by telling them a story about a crazy tour guide in this jungle, who used to lead tourists to the wrong places just to have them killed by wild animals.

The people in the nearby villages later caught him and beat him to death but his ghost remains in the jungle and continues to kill tourists.

The remaining group members figure out that Riya is dead and try to pull her body out from the well, while Dev suddenly notices that Kaali does not have a reflection in the well's water.

Terrified by this, Dev makes an excuse to send Kaali away by asking him to gather some timbers which can be used to perform Riya's final rites.

Dev shows the videos to Krish and Ishika, proving to them that Kaali is a ghost and is indeed responsible for all the mysterious deaths happening in the jungle.

Flashbacks reveal that the villagers did not kill Kaali but instead, took him to the core area where he was brutally thrashed and then thrown in front of a hungry tiger that mauled him to death.

The story shifts back to present day where Kaali’s ghost now standing by the well, expresses his immense anger and hatred for tourists who come to the jungle to hunt wild animals and disrupt their well being without any regrets.

[6][7] Planet Bollywood rated the film 5/10, stating," Soham Shah is as inept at directing performances as he is at writing an engaging screenplay or building any sort of momentum or pacing visually.

Lara Dutta cringes, cries, and yells randomly, while Esha Deol consistently carries a strange expression on her face that suggests she might have just swallowed a frog.

Ajay Devgan tries his level best to rise above the non-existent screenplay, but the daunting task of saving the film single-handedly proves too difficult even for him."

According to the Indian trade website Box Office India, with around 16,00,000 units sold, this film's soundtrack album was the year's seventh highest-selling.
