Shodh (1981)

Surendra (Om Puri), having been exiled from his village in youth and established himself in the city, comes back to the news of his father's demise, reportedly at the hands of a phantom. He announces a prize for anyone who succeeds in showing him a ghost, which attracts the greed of the poor hungry peasants, resulting in the accusations of innocent people as haunted and even murders with the hope of producing a ghost.
