The Medicine Seller checks into the last room of a traditional inn, just as a pregnant woman named Shino desperately asks for shelter.

She is given a secret room - a room possessed by a group of ghosts.

Four men should have turned up to the house of Lady Ruri in a bid to win her hand in marriage. However, one of them has disappeared, so the Medicine Seller takes his place in the traditional incense competition taking place.

The Medicine Seller unravels the mystery and finds the truth behind the passenger's stories.
