A man dressed like a Joseon prince arrives in modern Seoul, confusing locals with his old-fashioned appearance and ignorance of conveniences like rice balls and bathrooms. He asks a drama producer for help to reach the palace because he claims his father is the king. The producer suspects he's involved in cosplay or filming but soon faces hostility from others who view the man as an outsider and tell him to return to Joseon. The episode ends with the man firmly insisting that his bathtub is a gateway to Joseon, challenging the producer's disbelief and setting up further mystery about his true origin.
