Sakai is a city near Osaka by the bay famous for its swords in the old days and kitchen knives today. Norio is an antique dealer in the city. Sasuke is a potter in the city. Seventeenth century tea master Sen No Rikyu appears before them one day.—aghaemi

A dowdy antique dealer Norio finds a valuable tea cup of the most famous Japanese tea master Sen no Rikyu from the 16th century when searching inside a storehouse of a rich family. Norio deceives the homeowner Sasuke to get it for almost nothing, but it turns out that Sasuke is a mere house-sitter and the teacup is made by Sasuke himself. When Norio learns that Sasuke used to be a hopeful potter derailed by an antique authenticator Norio himself has a painful history against, the two decide to make the gamble of a lifetime against the authenticator they both have a score to settle with. Involving their wives and children, this act of fraud goes quite unexpectedly.—GAGA Corporation
