'Ashwatthama - Return of the immortal’ is a story about Ashwatthama, a legendary warrior from Mahabharat times who was born with a gemstone on his forehead and blessed by Lord Shiva to become an immortal. He had fought in the Mahabharata on the losing side of Kauravas.
After his despicable act of killing Parikshith in Uttara’s womb, Lord Sri Krishna takes away the gemstone on Ashwatthama’s forehead and curses him to live a miserable life for eternity with pain and stench. The gemstone taken away from Ashwatthama has many powers including ability to control Rudrasena - The army of Lord Shiva.
The gemstone considered as a symbol of power passed the hands of many kings through millenia and rested in the hands of an Aghori sect in the present times. Pashupati, an Aghori of the same sect who also happens to be a Geneticist uses the powers of the gemstone to bring a cataclysmic end to the world as it exists to usher a new world.
A reluctant Ashwatthama gets drawn into a battle with Pashupati after learning that the latter is using his gemstone to destroy the world by invoking Rudrasena. Whether Smriti and Ashwattham are successful in stopping the GM locusts from ravaging the world vegetation, whether Pashupati is successful in invoking the Rudrasena and whether Ashwatthama is able to stop Pashupati forms the rest of the story.
