Ranmaru, Hikaru and Kanji go to Yunishigawa hot spring to look for a geisha girl, Miyabi. At a hotel there, they spot Miyabi leaving with a man, but fail to follow her as their old car runs out of petrol. Meanwhile, Kanji asks a hotel manager, Misuzu to let them stay for free in return for Ranmaru working as a bathhouse attendant. Then the president of the local hot spring union, Ishihara, rushes in and tell them that a dead body has been found in the river nearby. All those things bring a great turmoil. -- TBS
