Bandh Darwaza

The film opens in the ruins of Kali Pahari where Nevla, a Dracula-like vampire, sleeps in a coffin by day and hunts villagers by night. He feeds on humans and craves a steady supply of young women to seduce and corrupt. Nevla is supported by a ragtag cadre of servants who lure victims to Kali Pahari.

From the shadows, Nevla's henchmen and the priestly conspirators lure innocent villagers to Kali Pahari for his nightly feasts. The gang acts as muscle and steering hand so Nevla can move freely without suspicion. The looming threat to nearby villages is established.

Mahua serves as a maid in Thakur Pratap's household, but her ties to Kali Pahari alarm the Thakur when he catches her with Baku. He warns her she will be fired if seen with the gang again. Yet Mahua remains bound to Nevla's scheme, tasked with sourcing a new maiden.

Sapna, Kamya, and Kumar attend Kamya's birthday party, where Kumar's growing affection for Sapna stirs jealousy in Kamya. Kamya taunts Sapna, souring the festive mood and hinting at deeper motives. The encounter foreshadows the darker forces at work around Kali Pahari.

On the way home, Sapna encounters a mysterious Kali Pahari-linked woman who demands the drop-off book and sits in Sapna's car. Separately, Kamya discovers the same book at Kumar's trail and realizes she can manipulate him through witchcraft. A road accident involving the stranger leads the trio toward Nevla's altar.

The stranger is taken to a ritual site where a priest uses black magic to heal Kamya's injuries, signaling the power of Nevla's influence. Kamya agrees to join Nevla's gang, embracing the path of Kali Pahari to gain control over Kumар. Her allegiance marks a turning point in the struggle.

Under Kamya's manipulation, Kumar is lured to a graveyard where she attempts to ensnare him with witchcraft. Anand and Sapna arrive and manage to rescue Kumar, exposing Kamya's treachery. They report the betrayal to the Thakur, escalating the stakes for everyone involved.

Kamya is invited to Kali Pahari for a late-night ritual to revive Nevla after years of slumber. Nevla recognizes Kamya, bites her, and she becomes his sex slave, forever trapped behind the bandh darwaza. The ritual solidifies Nevla's control over Kamya.

Kumar, Anand, and Sapna enter Kali Pahari to recover Kamya and find her barely conscious in a glass coffin within the catacombs. The place fills with smoke as Nevla and his henchmen close in, and Nevla abducts Kamya before the rescue can be completed. The event underscores Kamya's precarious fate.

The Thakur learns the truth about Kamya's birth and the bargain behind it, a revelation hinted at by Mahua's glee. Enraged, he executes Mahua to sever Nevla's manipulation, while vowing to protect Kamya and end Nevla's threat. The revelation reframes the mission with renewed resolve.

Nevla intensifies his assault, biting Bhanu and pursuing Sapna through the Thakur's domain. Kumar and Anand fight to shield Sapna while the townspeople grow increasingly terrified of Nevla's power. The chase drives the heroes toward a climactic plan to end Nevla once and for all.

Kumar, Sapna, and the Thakur re-enter Kali Pahari to recover Kamya, engaging the gang and Nevla in a brutal battle. They wound Nevla but cannot kill him, and Kamya is killed when spikes pierce her body during the struggle. The loss deepens the resolve to finish Nevla for good.

The tantrik reveals Nevla's Achilles heel: his soul is trapped in a statue, and sunlight is his weakness. The trio devises a two-phase plan to lure Nevla into the open and burn the statue with the townsfolk's aid. The statue catches fire, Nevla bursts into flames, and Kali Pahari's darkness finally ends as Nevla is destroyed.
