Arjun Verma's meticulously ordered life is shattered by a single, cryptic invitation to Hollow Manor. Expecting little more than an eccentric puzzle, Arjun convinces his impulsive best friend, Rohan, and the pragmatic Maya to join him.
But the manor is not a game. They soon discover other "chosen" guests—the skeptical journalist Neha and the historian Dr. Roy —and learn the manor's true guardians are hobbit-like beings who have been waiting for them.
The group has been summoned to fulfill an ancient prophecy. To restore the balance of the manor, they must face a series of trials that test their souls and confront the source of the shadows that threatens to consume the sanctum. But as the trials grow darker, a deception from within the group threatens to fracture their unity and fulfill the void's ultimate victory.
