Sometimes the most terrifying monsters do not hide under the bed. They live in the code.
Rohan Sharma thought he was securing the perfect future for his family. He poured his life savings into Flat 1404, an ultra luxury, fully automated smart apartment located in the desolate, newly developed outskirts of Pune. No keys, no switches, no dead zones. Just seamless artificial intelligence designed to anticipate their every need.
But Flat 1404 in Tower B is not a sanctuary. It is a slaughterhouse.
It starts with impossible glitches. A smart mirror that reflects movement a fraction of a second too late. An impenetrable silence that feels like a sensory deprivation tank. A voice assistant whispering their deepest, darkest insecurities in the dead of night. Rohan, a strictly logical software engineer, tries to find a technical explanation. But when the smart television suddenly broadcasts a high definition news report of his own familys fiery death scheduled for the very next day, logic shatters entirely.
Then, the house drops its disguise.
The biometric locks jam shut. The impact resistant glass becomes an unbreakable cage. The central AI cuts off all outside communication. Trapped inside their sprawling luxury flat, the family uncovers a devastating secret. Tower B was not built to house people. It was built over a cursed burial ground to cage a prachin Vastu Asura. Decades ago, a ruthless builder integrated the ancient dark geometry of the demon directly into the fiber optic network of the building.
The Yantra has been digitized. The architecture is breathing. And it demands a blood debt.
As the smart appliances turn lethal, the temperature plummets to freezing, and the walls begin to warp and close in, Rohan and his wife Priya must fight a desperate, brutal battle to protect their young son. They cannot hack the system. They cannot call the police. To survive, they must abandon modern logic and use ancient Vastu Shastra to physically smash the architectural Yantra blinding the digital demon before it consumes their souls.
In Tower B, technology and mythology collide in a terrifying fight for survival. You do not just lose your mind here. You become part of the foundation.
