Mantra loses her parents at a young age and lives with her friend Vinny. She inherits an ancestral property called Mantra Nilayam, located on the outskirts of Hyderabad. The property has gained notoriety as a haunted house following two mysterious deaths that occurred there years earlier. Unable to find a buyer due to its ominous reputation, Mantra struggles to sell the house.
A prospective buyer, a professor, agrees to purchase the property on the condition that someone lives there for three months. Mantra decides to stay in the house with her friend, but they are soon frightened by the presence of an evil spirit and vacate the premises.
Meanwhile, Hero, a small-time enforcer specializing in land settlements, approaches Mantra and agrees to stay in the house for the three-month duration, motivated by the promise of a commission once the sale is finalised. He moves in with three of his friends. However, one of them, Muniswamy, is mysteriously killed, prompting Hero to investigate the eerie legends surrounding Mantra Nilayam. The plot delves deeper into the house's secrets, its dark past, and Mantra's connection to the tragic events.
