Yamaoka and the "flower trio" are in Kamakura when they come upon a beautiful bamboo grove and decide to have a picnic. They meet the caretaker who tells them the forest is owned by Bitō, an owner of a chain of hotels, who intends to cut it down to build a villa. When Mr Bitō shows up, Yamaoka tells him off and says that a bamboo forest like this is more valuable than any building, but Bitō just scoffs at him. Back in Tokyo, Yamaoka asks president Ohara for a favor. Ohara invites Bitō and Itayama to dinner where the theme is Japanese sea bass.
