Ace detective Avinash Roy arrives at a sleepy Hill station in Sikkim in the fervent hope that holidaying at a secluded Buddhist monastery up in the mountains will work as a perfect antidote to his jaded, city-weary nerves. And surprisingly, it does. The crisp mountain air and Long walks through undulating valleys not only rejuvenates him, but also rekindles his libido, much to the pleasure of his wife. On their last night, Roy is faced with a strange request from the head Lama of the monastery. Apparently, a rare invaluable manuscript, the very existence of which is a secret, is missing from the underground vaults of the monastery. Could Roy retrieve the treasure without others knowing anything about it? As Roy agrees to help the senior monk, he soon realizes that the serene ambience of the place could well be just an illusion. Beneath its placid surface lurk intrigues, conspiracies, unbridled passion, ambition, religious extremism and elemental fear. Worse, Roy’s very life is in grave danger, hanging by the proverbial thread.
