A man gets rid of a cheap pot without knowing it contains a map to a treasure. As word spreads, many join in hunting it.

The Yagyu family's elder son sends an old and cheap looking pot to his young brother, ignoring that the pot contains a map showing where it was hidden a treasure of a million ryo. He tries to recover it but his brother's wife has sold it to some junk dealers. Finally the pot ends up in Yasu's hands, a kid whose father was killed although Tange Sazen was supposed to protect him from in his way to home, so Tange Sazen will look after Yasu.—Melmoth
