Plot Summary

At a time when maps weren't readily accessible for the public, 'Gosanja KIM Jeong-ho' (CHA Seoung-won) sets out to walk across the Korean peninsula to make the Daedongyeojido - the Great Map of the East Land, with hopes of providing an accurate and accessible map for the ordinary people. He has all but forgotten about his daughter KIM Sunsil, who grew to be 16 years old in his absence, as he focuses on completing his map. People say he is crazy, but driven by his goal, KIM Jeong-ho endeavors to complete the template for woodblock printing of the map. However, Daewongun, the King Father (YU Jun-sang) seeks to take KIM Jeong-ho's map to gain the upper hand in his power struggle with the House of Kim of Andong.
