The Islamic state has spread its tentacles in India, penetrating stealthily into the academia, media and politics. The mastermind is Shamsur Ali, a physicist from Bangladesh. To destabilize India, he wants to create a sort of apocalypse, which the 21-year-old Kubha must prevent at any cost, come what may.

In a brazen attempt at legitimizing the demolition of one of the most prominent historical structures in India, someone unbelievably, it could be both Hiranyagarbha Bharata, a radical Hindu outfit and the Islamic state resorts to a big deceit. Afsar Fareedi, a linguistic paleontologist, catches the fraud. In the melee, there are three gruesome murders, including that of her father, perhaps to eliminate all traces of a carpet which, Afsar discovers, has a lot hidden in its mysterious motifs. At the centre of all this is a verse composed by the maverick mathematician, Aryabhata, some 1,500 years ago.
