Just days before their wedding, Crown Prince Lee Gak's fiance is found dead by the palace pond. He then called for three of his trusted retainers to help him solve this mystery and punish those who commit such a crime. But before he could get anywhere, suddenly he's become a target and was forced to leave his palace. Somehow with trying to escape alongside his retainers, Lee Gak ended up 300 years into the future (or present day Korea).
Since they're not used to the present time technology, culture and mannerisms, Lee Gak and his group are totally confused until they met Park Ha. Hilarious antics ensue when the old customs of the past do not sync well with modern life. Besides getting used to things, they must figure out who murdered his princess and tried to kill him as well.
