Oichi, the blind bounty hunter, frees a woman from unjust prison and is now hunted by order of the local magistrate. She is concerned with the poor fishermen, who are oppressed and robbed by a gang in collusion with the authorities.

Oichi the Blind helps a woman escape the clutches of a high government official to go off with the man she loves. The official puts a reward on her head of fifty gold pieces and soon a menagerie of bounty hunters are after her skin.
