[4][5][6] Typical of Ramsay's other works, the film chronicles the story of a demonic magician Samri who after a violent standoff, curses a king that every female member of the latter's family would die at childbirth.

[7] The film opens 200 years ago, with the royal procession of Raja Harimaan Singh of the sultanate of Bijapur, stranded near the Kali Pahari (the Black Mountain).

While the rajpurohit (royal priest) suggests Samri to be burned alive as it was believed that fire purifies the soul, the Raja proposes another sentence—Samri is to be decapitated, with the headless body to be buried behind the old temple at Kalighat and the head secured in a strong-box to be kept at a secret chamber in the Raja's haveli (mansion).

Anand and Sanjay smash the wall behind the painting and uncover the strong box that holds Samri's head.

Misunderstandings and tensions claim the lives of many townspeople and Anand meets a horrific death at the hands of Samri.

After a series of tumultuous events, Sanjay manages to trap Samri in a coffin and, with the trishul in hand to check the monster, drags him out to the village square (next to the old temple).

The complete soundtrack is as follows: Made on a budget of ₹2.5 lakh, Purana Mandir collected a total gross of ₹2.5 crore.

Purana Mandir was released on DVD by Mondo Macabro as a double feature with the 1990 film Bandh Darwaza (also directed by the Ramsay brothers), as the Bollywood Horror Collection Vol.

[9] In 2023, Mondo Macabro released Purana Mandir on Blu-ray as part of the Bollywood Horror Collection boxed set, which also includes the Ramsay brothers-directed films Aatma (2006), Bandh Darwaza, Purani Haveli (1989), Tahkhana (1986), and Veerana (1988).
