At the cusp of the founding of Joseon Dynasty, an envoy from China is delivering Emperor’s Ming’s Royal Seal. But nature in the form of a giant whale intervenes and swallows the royal seal. When a generous reward is offered to whomever can retrieve the royal seal from the belly of the whale, the race is on. A group of mountain bandits led by Jang Sa Jung and a group of pirates led by Yeo Wol go after the lost treasure, but who will get to to it first?

Trivia, insights & behind the scenes
The production built four full-scale ships for authenticity, including a 32-meter pirate vessel that required 150 crew members to operate.
The Ming seal represents real historical tensions—Korea's Joseon dynasty carefully navigated Chinese suzerainty, making this 'lost treasure' a sly commentary on colonial anxiety disguised as popcorn entertainment.
