Kannappa narrates the journey of Thinnadu, a fierce tribal hunter who lives by instinct and rejects all notions of divinity. Far removed from faith, his world changes when he stumbles upon a silent Shiva lingam in the forest. What starts out as defiance slowly transforms into raw, unconditional devotion. With no knowledge of rituals, Thinnadu worships in his own uninhibited and heartfelt way. When Lord Shiva puts his devotion to the ultimate test, it leads to an act of sacrifice so powerful that it stirs the divine itself.
