Tahkhana (transl. Dungeon),[1] also known as Tahkhana: The Dungeon, is a 1986 Indian Hindi-language horror film directed by Shyam Ramsay and Tulsi Ramsay. Its plot follows two sisters separated at birth and the search for a hidden treasure, which is guarded in a dungeon by a bloodthirsty monster.
A dying Thakur Surjeet Singh bequeaths his entire estate to one of his sons, Raghuvir, disowning the other, Dhurjan, the family's black sheep, who also indulges in black magic. The latter swears to use magical powers to usurp the estate, and arranges the abduction of Raghuvir's daughters, Sapna and Aarti. Mangal and his men manage to apprehend Dhurjan, imprison him in a dungeon, and rescue Aarti. They are unable to locate Sapna, and Raghuvir is killed. Before dying, he informs Mangal that Sapna has one of the two pieces of a locket around her neck, while the other is on Aarti's, and when joined together will reveal the location of a treasure buried in a dungeon.
20 years later, Aarti and her boyfriend, Vijay, along with several others, attempt to unearth this treasure - not realising that they not only face betrayal from one of their own, but will also release and fall prey to an ageless and indestructible evil entity.
Tahkhana was released on DVD by Mondo Macabro as a double feature with the 1993 film Mahakaal (also directed by the Ramsay brothers), as the Bollywood Horror Collection Vol. 3.[2] In 2023, Mondo Macabro released Tahkhana on Blu-ray as part of the Bollywood Horror Collection boxed set, which also includes the Ramsay brothers-directed films Aatma (2006), Bandh Darwaza (1990), Purani Haveli, Purana Mandir (1984), and Veerana (1988).[3]
