In the bustling town of Madurai, Arjun (25) , a skeptical archaeology student, and his childhood friend Priya (22) , a spirited folk singer, return to Thiruvasal to document local legends for Priya’s music album. Their journey is haunted by cryptic warnings from Arjun’s grandmother, Amma (90), who speaks of the Jeeva Thiruman —"the Living Shadow"—a primordial demon born of fear, sealed in a cave by a Tamil king 2,000 years ago.
