The Last Fortress

She died once at the end of the world.

She came back with one year left to change everything.

On August 15, 2033, Dhruti Pandya opens her eyes - not on a hospital bed, not in another life - but in her own apartment in Surat, Gujarat. One year before the apocalypse swallows the world whole.

Dhruti stares at the footage for a long time.

She doesn't forgive easily. She doesn't trust quickly. But s
