In 1388 the Joseon Dynasty is on the verge of becoming official and all that is left to make it official is the Royal Seal of the Emperor and the name. Everything seems like it will happen but a very unexpected event takes place that changes the course of the Royal Seal. While at sea the Royal Seal somehow ends up in the passion of a whale. How it got there is being kept a secret but the hunt for the whale and the Royal Seal is no secret at all. Pirates, gangs, and every other type of person that wants the seal is now out on the hunt for this whale that has the Royal Seal.
